spy, for so many reasons (tactics, stealth, and mind games to name a few), although i didn't start out this way. my fall back is demoman for defense, but i've been trying to play other classes lately. pyro is a lot of fun under the right circumstances, and i've had some success there. heavies can be fun, but they're awful slow. i'm rubbish as a sniper, though i intend to improve on that. i don't play scout much either, but i've had fun playing late-night on quiet servers running fast very fast and batting people (original bat, not wood). medic makes me feel useful sometimes, but i die with ubers a lot, and the k/d ratio makes me sad. i do like to play engineer sometimes, as i like to see my teleporters approach 100 teleports. i'm not particularly good with the soldier either, although they can be devastating when used well. no matter what my intentions, though, i usually end up playing the spy most of the evening.
