Hello there fellow MMO-ers
In this post I would like to analyze Siege of Oggrimar bosses and the talents that i pick in each fight. Notice that this isn't an absolute guideline of course, and if you have another prefferance feel free to comment so we can have a nice discussion going. I will not handle the Tier 90 talents are those are spec dependent.
Edit: This concerns Frost Mage Specialization
Immerseus
-Blazing Speed: As you don't have to move extensively during the fight and the only real movement happens when an extensive amount of blobs spawns away from you you should pick this to close the distance fast.
-Temporal Shield: This is extremely useful during Phase 2 as you remove a huge burden from your healers and it is not on the GCD so you can use it during P1 without repercussions.
-Frostjaw: Sadly ring of frost doesn't work on the Sha Blobs, so you should pick Frostjaw just in case that wild blob is about to hit the pool.
-Greater Invisibility: With this talent you make a hitting swirl cause minimal damage
-Living Bomb: There is mostly single target damage needed in this fight and even in P2 it takes way to long to dot all the blobs up so you use LB for the single target damage increase it offers.
On Heroic mode you should use Greater Invisibility to remove the damage over time debuff during your burst so you can have 100% of your dps on burst. Also note that you can swap Frost Bomb for Heroic Mode as together with pet freeze you can almost solo the stacking adds. The Single Target dps loss exists but you are not going to reach enrage because of it
Fallen Protectors
-Blazing Speed: Icy Floes is also viable but they both serve minimally in this fight. I like the bursty speed of BS and that is why I generally pick it.
-Temporal Shield: It helps with the Calamity damage and the Inferno Wave during Rook's Desperate measures. Ice Barrier is quite alright as well but remember that it is on the GCD.
-Frostjaw: You have an extra interrupt for the Embodied Gloom cast
-Greater Invisibility: Survivability and the fact that it removes He's debuff
-Living Bomb: You can use Nether Tempest just as well I haven't noticed a significant DPS difference. It varies on every fight. Remember to dot everyone
On Heroic Mode you should use Greater Invisibility to remove He's debuff as soon as it comes on you unless you are behind on DPS. Then you should use it on the stacking Calamities. Only use Ice Block for the Embodied Anguish soak.
Norushen
-Blazing Speed: Makes it easier to run around the mobs in the trial section of the fight
-Ice Barrier: There is no bursty damage but more of a consistent damage intake. That's why temporal shield isn't as handy.
-Frostjaw: Not a very important talent in this fight
-Greater Invisibility: You can also use Cauterize as there is no damage taken burst. Personal choice.
-Living Bomb: The hardest part of the fight is when the fight reaches it's end where you want the most of the damage on the boss. Nether tempest is OK, but if you struggle on dps it's preferred that you pick LB.
No particular tricks or tips for Heroic mode. If someone has one please fill me in and I shall edit this
Sha of Pride
-Icy Floes: There is limited movement in normal mode so Blazing Speed is not necessary.
-Ice Barrier: The damage from Swelling pride is 255k damage. Ice Barrier if combined with Trinket procs can soak up to 230k. Temporal Shield would block 0.15 * 255k = 38k damage. As every Swelling Pride is usually handled by healer cooldowns the Healing effect of TS is probably going to go to waste.
-Ring of Frost: AFTER the tanks have picked up the adds, drop it under them follow up with blizzard and enjoy
-Greater Invisibility: If you have Gift of the Titans and a Mark of Arrogance, or if a healer is on high pride you can use this to remove the Mark. Also due to the 1.5 minute CD you can use it on every second Swelling Pride.
-Living Bomb: Strongest single target.
On Heroic mode there are many talent choice changes that are necessary (mostly on their use). Use Blazing Speed instead of Icy Floes in order to soak the Rifts fast and be back in position. When soaking the Rift use Ice Barrier as it negates roughly 80% of the damage from Collapsing Rift. During P2 you should use GI, Ice Block, GI in order to soak 3 subsequent Swelling Prides. This minimizes the strain on your healers.
Also note that you should for no reason put RoF on the spawning place of the small ads.
Galakras
-Blazing Speed: There are several moment when you need to be somewhere fast.
-Ice Barrier:There is never a high enough burst for Temporal Shield to be usefull except during the last phase but we handle that with Greater Invisibility.
-Frostjaw: Extra interrupt if someone fucks up.
-Greater Invisibility: Removes the Fire Debuff during the Dragon Phase and greatly minimizes the damage.
-Living Bomb/Nether Tempest: Living bomb is going to offer you more damage on Galakras so take that if you struggle as a guild on P2. Nether Tempest speeds up P1 a little.
On Heroic if you are on Grunt duty use Frostjaw on the Grunt to keep him away from the siege gnomes.
Iron Juggernaut
-Icy Floes: There is quite alot of sidestepping Borer Drills and Cannons and Kiting Lazers that this is helping you maximize your dps.
-Temporal Shield: Greatly helps during P2 as it is high consistent damage.
-Frostjaw: Of 0 importance
-Greater Invisibility: Use for soaking mines if necessary and negating Shock Pulse damage.
-Living Bomb: Single target only fight so LB is the boss.
On Heroic mode there are some important changes you should keep in mind. Replace Icy Floes with Blazing Speed for those O-shit-O-shit moments and in order to reach the boss faster after P2 (assuming you do the cheese mechanic). You can use Greater Invisibility instead of Cauterize for the Shockwave but that is personal preference. Both have their uses. Remember to DoT the boss up before you get knocked back and out of range.
Dark Shamans
-Blazing Speed: Helps out when you get Mist tornadoes close to you. Icy Floes is of use as well.
-Ice Barrier: You can't expect the damage in this fight so just keep Ice Barrier up as often as you can
-Ring of Frost: You can bother to use this on the Green Slimes. I personally can't.
-Cauterize: This fight is a clusterfck on Normal so it's the unexpected that kills you.
-Living Bomb: Excellent 2 target cleave. During the Doggy part just Dot the 2 dogs and 1 shaman.
Heroic is far less of a clusterfck so that reflects on your talents. Take Greater Invisibility for the Iron Prison mechanic or to reduce damage from Toxic Mist if you are on that group (not sure if it removes the debuff).
Malkorok
-Blazing Speed: To soak emergency puddles.
-Ice Barrier: To reduce damage from the puddles.
-Frostjaw: Not important
-Greater Invisibility: Reduce damage from puddles.
-Living Bomb: More damage on Malkorok so you end the fight quicker and there are less puddles.
A lot of puddles on this fight. On Heroic you should use Ice Barrier to soak one Orb during P1 right after the puddles have spawned and you are not on puddle soaking duty at that moment (aka it's not on your pizza slice). The Ice Barrier absorption and the damage from those orbs is equal. During P2 use GI and Blazing Speed to soak the most Orbs possible.
Spoils of Pandaria
-Blazing Speed: Fast Klaaxi bomb drop and return to position.
-Ice Barrier: There is not much high burst or high consistent damage going on so it outvalues Temporal Shield.
-Ring of Frost: You can frost the quilen dogs but it isn't that much of a deal.
-Greater Invisibility: With this you can soak the Klaaxi bombs and greatly reduce the Damage from the bosses in the Mogu side
-Nether Tempest: You dot everything up and top the meters.
On Heroic you should use Temporal Shield instead of Ice Barrier as Mogu has very high burst and Klaaxxi has extremely high ticking damage.
Thok the Bloodthirsty
-Blazing Speed: Very useful if you are the last target of the Fixate phase
-Temporal Shield: As there is damage every 2.4 seconds that also interrupts you, you can not waste a whole GCD on Ice Barrier when it's going to get broken immediately after.
-Frostjaw: Not important
-Greater Invisibility: Removes the debuff during the Acid Phase
-Living Bomb: Highest single target
Siegecrafter Blackfuse
-Icy Floes/Blazing Speed: If you are on the belt IF is a must. If you are on the boss then both are very good and you should just pick whatever you prefer.
-Ice Barrier: Keep it up whenever possible. Haven't found much of a use on Temporal Shield except that it's not on the GCD.
-Ring of Frost: Use it on the mines.
-Greater Invisibility: Removes the laser debuff if you happen to receive one.
-Living Bomb: Highest single target
On Heroic mode you should have the same talents but you must be more careful in using them. Use Greater Invisibility only when you are forced to run through a laser during the Empowered Laser + Empowered Magnet phase. Use Ice Barrier before you enter the laser to drop the Saw blade so you minimise the damage and GI after to remove the DoT.
Paragons of The Klaaxxi
-Blazing Speed: Get in range of a blue catalyst or in the Aim.
-Ice Barrier: Use it on cooldown. Haven't found a use for Temporal Shield yet.
-Ring of Frost: Not important as it doesn't freeze the bloods.
-Greater Invisibility: Completely removes the Aim effect from you so should be picked at all times.
-Living Bomb: This isn't a multidot fight so you should take the best single target spell you have.
Use the exact same talents on Heroic mode.
Garrosh Hellscream
-Blazing Speed:Very handy for dropping Desecrates far from the raid and return back in position. Also right after you return from the Realm of Ysh'jaar you are dropped in the middle and with most tactics you are required to get to a far away marker.
-Temporal Shield: Handy for Intermissions and Whirling Corruptions.
-Frostjaw: Extra interrupt for the Shaman
-Greater Invisibility: Minimizes the damage from all sources.
-Living Bomb: Most of the fight is single target and you should use single target bombs.
On heroic mode you must use the above talents. Use Blazing Speed also for P4 if you get targeted by the Iron Star. Also usefull for the Temple of the Jade Serpent intermission if you are assigned far away. Use Frostjaw and Counterspell to interrupt the first two casts of the shaman mob (ask your raid for that assignment).
This took me several hours to complete so I hope you guys have a use of it. If you have any disagreement feel free to post and I shall edit whatever I agree with.
