For all the moaning about the 24 man raids, people being complete tools are an exception, rather than the rule. At least in my experience! The same can be said for regular dungeoneering and such. Rare are the times when people just plain suck rather than being below average, and even rarer still are complete failures.

Besides, when healers DPS, you murder kill the trash to death, instead of just defeating it like a bore. Who wouldn't want to be that METAL?!
