Note: I haven't seen any recent videos of Jin, but hopefully someone can tell me that I'm an idiot.
Is it me or does Jin hit like a girl?
Also, I think his dust is somewhat useless, considering it seems like you can't really use them in a combo chain. The dust moves itself are too slow and have too long recovery to really be used for starting a combo, yet it can't be used at the end of a combo for a continuation.
Also, his projectiles aren't fast enough when coming out imo.
