I only either heal or tank, and I PuG a LOT. I enter every one with a good outlook, and almost all of them are great. More often I find outstanding PuGs vs horrible ones. And even the crappy ones... well, I just leave.

So when I read about a tank complaining that they will never run a PuG, I say get over yourself. As one of the most needed roles, you can kick whomever bothers you and no one is going to argue. I have literally told a guild of 4 that either their friend beats it or I'll leave and they can wait for the next player, and they kicked their own guild member for being a jerk.

Maybe when you join a PuG, talk to the members. Ask how they are doing today. Make some conversation. Most people join the PuG and treat their fellow players like NPCs unless they are not happy in which case they just bitch and complain then. If you are like that, no wonder you hate PuGgin so much.

In the end, I'd rather the ego-inflated tanks and healers stay out of the queue. If the rewards don't feel like a nice perk, then whatever. And if the whiny DPSers quit because they don't get the perk, all the better too.
