Which classes/specs are the best at bursting down priority single targets / short lived aoe packs? Another way to ask is which classes/specs are currently the best at target switching and bursting down said targets?
I've played a ramp dps class that is poor at target switching for a long, long time, and I'm curious which classes and specs are on the opposite end of that spectrum currently?
Frost DKs with Pillar/Killing Machine/Chained Obliterates? Destro locks with chained mana tapped Chaos Bolts? Rets with whatever it is rets do now? I'm curious for short lived aoe packs as well, though I have no idea what the state of any other class/spec's aoe is.
edit: This is mainly within the context of raiding. i.e. who in your raid comp would you primarily depend upon to burst down priority targets (assuming it's not simply all dps switching)?
