I have found a bug, where if you put a heavy weapon as default, you will get it even thou you are not playing the heavy body
Ive seen this too its realy quite a anoyning when people do that. . . i know how to do it a buddy of mine told me bui never do i feel like its cheating and the only reason i get mad it the heavy has on flaw his speed make him more pron to flanking if you can killing the big guy is hard face to face. . . so if he can run with most peole toe to toe the heavy is an unstopable force in this game.
