I find it funny that groups at 80 complain about lack of healers. Who has the easiest time of leveling? DPS. You rushed to 80, most likely not helping out any healer you passed by on your way to the end. What did you expect?
As someone still fairly new to the dps side, I see firsthand how it is now. We have it easy in the leveling department. Our gear is made for maximum dps, our spec is, our class is. So Mr. Warlock, quit pressuring Mr. Priest to hurry up and level. Instead invite him to one of your killing sprees. Mr. Rogue are you doing a quest you could solo? See if a healer has that quest too. Or has spending hours in LFG left you uncharitable?
