While true, there's a whole lot more of us that don't care what you bring to a TF or how you build as long as you're not an asshat and have fun. Mostly because we CAN just run to the end without stealth, not die, and ATT everyone should the team WANT to do that instead of just slappin down everything in the way, as I prefer.
I've only got 4 people on my gignore list so far and not one of them got that way because of something that happened while I teamed with them. But if someone were to say to me "you're a selfish player because you didn't take X, Y or Z powers/pools," they'd be on that list immediately. Cuz those people just suck.
