seconded foreverzz
but the probably I have with Bang is this:
he is fundamentally (ie stats and shit) broken (exaggerating a but).
he's a lightning bruiser, meaning he has above average everything (except maybe speed) as compared to the mario/jack (Jin) who is average in everyting. The standard way to balance this is to lower things like meter gain, less powerful normals/specials, less powerful supers, etc.
Meter: I think it's average but I haven't checked
Specials/normals: 5A to 5K, and maybe GP's.
supers: he has 4: one is safe on block, one is meh, the other 2 are Ragna's distortions but better.
this is my opinion and it is biased by my Jin rage of him being better in everything.
I think he just needs to be focused on his stats, he's got good damage and defense without sacrificing speed, and he has above average guard primers, he basically can do whatever he wants with impunity. His only limitation is his nails... but that isn't a problem since he doesn't have rely on them the same way say, Jin relies on heat.
but this is my opinion, it's not like he's uber broken, just slightly, within acceptable reason and these things always happen in fighting games.
