dungeons/raids mechanics you can skip with enough ilvl

[LalaRu]

Classic example is Turn 2's boss. Wait for him to enrage, then just kill him. Forget all that plague stack management.

Not a great example, because you need wait 12m first, then make the kill. If you manage Rot, you can kill it in 3'36" ending everything from start to end in 7'. Today, I think much less, as long as from video to today, we got +20 armor ilevels patches. But not any skipping of mechanics.
