I would prolly have kicked you freom the guild when you "benched" yourself if i were your GM. If you cant get into your head how important it is to think in the lines of "how can i carry my team more, to get the boss down" rather than "Why cant they carry their own weight so we can kill the boss" then i doubt theres much reason for you to play a multiplayer teamgame.
You just sound like an asshole with attitudeproblems. Grow up and be a proper human being, its not really that hard if you try.
