Checking your logs its only natural to let you go on the adds as you are the only aoe person in the raid thus its very easy for you to rank when you deal 75% of your damage on the adds, you would've pulled ahead with GoSup then, because 75% of the damage you did was on aoe targets. And you see the same tendancy on most other people who rank... they let you deal 50-80% of the adds all by yourself and let everyone else handle the boss, and you easily do around 400-500k. And you can also see the top dps using the GoSup observer. It might not be so much, but at least its a 10-20k dps increase.
The actual throughput from pets is much more variable than the differences based on absolute averages would show by several orders of magnitude; with that in mind I feel like most encounters offer opportunities for extra throughput by stacking Service with procs, cooldowns and vulnerabilities (something simcraft doesn't account for), or through avoiding damage lost during downtime - even if you and your pet aren't hitting the boss, the cooldown timer is still ticking.Please explain your choice of go serv with destruction? I can only seeing it be viable for demo due to the synergy between goserv and your mastery.
The only fight where changing a glyph or talent is huge would be Thok, get the glyph that makes Unending Resolve a 2 min CD so you can use it more and cast during the interrupts. If you know where you guild devo auras you can get a lot of casting in. Glyph of Curse of Exhaustion is good for General Nazgrim to slow the assassins and it is a good Affliction fight. I play pet sac for every fight I play destro on. On AoE fights I like to use the AoE to get a lot of embers and then use them to CB the adds/boss that needs to die. You aren't going to wipe on Galakras or Sha of Pride because you didn't have enough add damage but you will wipe if you can't go up the tower because the npc died or someone dies in the maze (people get sent to the maze right after adds come out).
It's nice if you can play more than one spec. I know that specs aren't technically talents anymore but destro isn't perfect for every fight and locks have it easy with their stats so you don't have to go to town or anything to regem/reforge.
I do every fight with soullink (except thok with pet shield), and every fight as destro with sac (except fel imp for thok, and eyeball for interrupting mc's on garrosh). As demo I use supremacy on thok/klaxxi, everything else service.
UR duration glyph for thok, everything else is 10% mitigation glyph.
I never play affliction - nothing against it, just since I feel I need demo for klaxxi, and destro for siege/garrosh, I cbf respeccing for the second night.
MF is about as useful to destro as KJC is for demo, which should give an idea of how useful MF is for destro, it isnt worthless but its close.
That´s no "I read it on guide xyz", thats simple logic. Rain of fire does nearly no dps since it´s mainjob is to generate embers. double this damage and it will still do nearly no dps. You´ll just get WAY more dps from KJC or AV. Trying it out on a "real" bossfight is definitly not the right way. Just do 5 tries with the same setup, and I bet the dps differences are about the same as from switching KJC to MF
I can't think of any encounter in SoO where MF would lead to a net dps increase over AV for Destro, at least not in any strategy I've seen. I'm not a big fan of KJC for Destro either, since it doesn't help you one bit if you get a proc during movement; you won't be able to Chaos Bolt anyway.
