I've never been able to play an MMO that doesn't have the trinity. Everything always boils down to ping-reliant i-frame twitch gaming or self-heal potion-chugging zergfests. {Thanks for the offer, but I'll have to pass.}

EDIT: why does giving each class unique niche utility somehow translate into people wanting a removal of the trinity, OP? Not sure how you made that logic leap there.
