TO MAKE IT MORE CLEAR:
I am asking what gimmicks exist for Tier 12 raids. Tier 12 gimmicks is the one and only topic in this thread. Please avoid getting off topic.
So far:
Alysrazor: Arcane mage OP dmg
In Tier 11 raids, there are quite a few class reliant gimmicks or strategies that make the fights significantly easier. Do any similar strategies exist in 4.2 yet? If so, which classes/specs would be enough, so that I can do efficient further research, but as much accurate info as you can provide would be beneficial.
To be clear, I do understand that these are not the only strategies, and that a good group can do bosses even without such gimmicks. On the other hand, you would have to be an idiot to not believe that there are (often significant) advantages to these methods.
Some examples, for those who would like either a list or clarification:
Heroic Conclave: A Rogue to cloak off stacks and stay on rohash the entire fight. Also, using a DK to tank the lashers and simply eat the explosions with AMS.
Heroic Magmaw: A Frost DK to kite parasites.
Anything with interrupts: Shammy.
Heroic V+T: Sub rogues for the shadow realm.
Atramedes: Rogue for gongs.
