1. you mean how talents are two choices and how artifacts gave you 0 choice?
2. you obviously havent looked at them, for example here is some cool ones for warlock, some effect you some dont
Accelerent makes you want to try to keep this buff up constantly
CC makes you to want to snapshot your UA just before your other UA ends
CI makes you have a chance to make your next incin instant, not huge but does change things up
CC allows you to do extra damage on your next chaos bolts after summoning infernal, pair this with the "While your infernal is summoned, chaos bolt does more and more damage for each soulshard spent" boom mega damage
DM pair this with soul conduit and banm you got lots of soul shard refuding, a 5% and a 15% every soul shard spent.
DP not exactly amazing but will make drain life actually useable if your at low health
DC this is super good, if you pair this with lots of haste, you can get the cooldown of your summon darkglare super low!
FK you dont ever cast demonbolt hard cast, so this changes your rotation to make it worth while to fire it off when you get this proc!
IV this one actually makes drain life a good damaging spell every so often, so every lets say 50 seconds a 400 damage extra drain life, meaning extra healing too
lifeblood this one is really cool, it makes you want to use healthstone as an actual defensive cooldown other then just a little heal, as this will allow you to heal through some constant ticking damage by healing yourself.
MF like the other this allows you to refund soulshards, however this one is more based on aoe, allowing you to refund more soulshards as long as there is more targets
RH this has amazing cleave potential, get some good haste and just BLAM BLAM BLAM
SB This gives you the potential change to your rotation, causing you to hold your demon bolt charges until you dreadstalker then launch of all off
SO THIS IS MASSIVE start with 4 stacks, this is a massive damage increase for affliction, if you enter a battle starting with 4 that is huge
SC This allows you a longer duration burst, aswell as giving you abit of bonus soul shards after your demon drops.
UB ok this is the only one that does literally nothing other then "extra damage"
WB THis allows you to in large aoe situations to gather lots of cool int buffs!
EP makes you want to try to optimize the buff, making sure you blow up imps for the haste buff
THere is more but its hard to find them as the wowead thing is still abit buggy.
this does not even include some of the cool neutral triats like these ones here that i find super cool
(Numbers are wrong but this here is fucking amazing)
(Makes aoe heal useful in single target healing situations)
3.green gear only has 3 rows, blues and purples have 4 rows and some raiding gear is said to have 5 rows.
