I have to confess something: I love playing Gill. Not because he is cheap, or broken, or retardedly overpowered. (Even if he is all these things.) I play him because I love his playstyle.
I sincerely hope Gill returns in a future SF game, in a non-broken form. He may not have the greatest design of the SF cast, but damn he is fun to play.
Would anyone else here try picking up Gill if he returned in a new game as a balanced, tournament legal character?
