The way I see it, we'll be zoning a lot more than pressuring.
faster jD and new jC could shape up to being good for air zoning tools, if A dp is just as fast it'll could still be a decent-ish anti air, just gotta weigh the risk vs reward more opposed to throwing it when they're inside air space that'll leave you safe on IB.
B ice car not knocking down could be advantageous if that's how it turns out, doing an air combo into b ice car that knocks them away and forcing them work their way back in.
On offense, I'm sure there'll be percs from new moves, new al beit, less damaging combos, not that this really bad as it seems everyone is gonna have damage nerfs.. I really hope that the new C ice sword is comparable to CSE on oki.
On the whole, I don't think Jin is going to be that bad, his overall game is going to be different, not necessarily bad though.
