Just because a character doesn't look good on paper doesn't mean they suck. Sometimes you just have to play with what you know and what you like until you get it right and people are proving it at tournaments.
For the people that say Hitomi sucks... I point you to LordXav1er. He got a match on Sio-fucking-logica. My next target is people that say Marie Rose sucks. UHHHH no. You need to train and get better at the game.
