Someone asked me an interesting question this past week, "How has DPS changed in WoW?"
At first I didn't know how to answer, because I didn't really have an idea. I've been raiding seriously since mid-WotLK, so I'm withdrawn from any Vanilla and TBC experience - but from my experiences - being a DPS has always, to me, meant how much damage can I do (understanding rotation and maximizing damage), without taking damage (fire is bad), while using my abilities to most benefit the raid (perhaps raid CD's).
Any thoughts on the evolution of being a DPS?
