The problem is enrage timers. Honestly what is the purpose of these? Why should it matter how long it takes us to defeat the boss as long as our team manages to survive. It's the enrage timers that cause harsh dps checks. I can't tell you how many tomes I almost beat AS3 but wiped only because we hit enrage. Seriously; I think raiding would be a lot more enjoyable if we removed enrages.
