I largely don't play TF2 anymore, due to my computer being a PoS and some annoying errors I get a few minutes after joining a server.
Favorite class to play, would have to be a tie between Demo and Pyro. I end up playing Soldier more since I'm better at him, and Engineer and Medic since my team generally never has them.

Thanks for the LULZ, I heal, you kill :3

KEEP UP THE KILLING, SON. YOU'LL DO RED TEAM PROUD. (Just pretend I'm the Soldier and not the guy who runs an answer blog for him)

EEUUUUUUGBHHHHHHHH
