Mostly medic and part-time Soldier. Either I'm healing/buffing you so can survive long enough to finish objectives (and shoot things)
or, I give you more ammo to shoot things.
I have no idea what body type to go for until I get my hands on the game. For all I know, I may end up being a Heavy Medic, lol.
But I usually move a lot in games and usually do long-range and
I tend to choose the "weakest" character types (ex: Princess Peach and Jigglypuff in SSB:M and any weak magical people with less HP in most RPG's)
in most games for some reason. (Also, coincidentally, since I play female characters a lot, so I end up choosing the weakest characters of the game anyway, lol.)
