Its funny that you only mention fights where there are adds to kill. Any Single target fight that does not have a mechanic for a tank to gain insane damage (I.E Feng with reversal) then a DPS that gets out damaged by a tank needs to re-roll.

Do you know how vengeance works? If you do not constantly get hit for the amount of damage that is causing you to gain 200k AP, you do not keep that 200k AP. Roll a tank and watch how quick that 200k AP drops back down to maybe 80-90k AP because you are not getting hit for 2 million unmitigated every second.
