I'm not claiming to be the best player out there by any means, but I am totally comfortable playing at least 2 characters from every role in high GM/low Celestial lobbies and have put in the hours to hit Lord on those characters. Lord means jack shit about skill, but I mean to say "I have a lot of hours in these different points of view." I can say with full confidence that healers are the most carried role, and the most retarded population. Consistently they have the aim, coordination, and awareness of a tank or DPS player a tier or two behind them. Plat healers aim like a silver. GM healers make panicked mistakes like a plat. If there's a retard on your team, bully them onto healer because that's your best chance to carry him. If your team is retarded, go healer because that's your best chance to carry them. I'kll warn you though, learning healer curses you with the knowledge of how hard it isn't and therefore how retarded your team must be to fail at it so much.
