Just came back from a bunch of matches with a local Jin player who has a lot of Arakune experience, more experience than I have with Jin. I'm not 100% on the changes with Jin and I think I respected his pressure way too much like it was CS2.
Fighting Jin is a bit arduous, he has pretty good space control and he's fast on the ground. He controls the air directly in front and above/below him and can convert most random hits into 3k with decent oki. Blocking jin isn't that bad, his high low mixup is predictable but his crossup game is pretty good, though for the most part I wound up IB his crossup j.B since I was doing it on reaction. He still has some of the fancy blockstrings from CS2 like: [starter] j.C, j.2C, AD, j236D or something like that. Getting curse on Jin is annoying at times, if he decides to play at full screen, since j.D doesn't go full screen, slowly work him to the corner. If jin decides to rush you down play keep away and make sure you watch your barrier and jin's heat. Ice wave destroys ranged characters and puts characters in a crumple state which allows jin to combo. Try and bait the hell out of jin's DP's, if you have him on the ground if you're coming in from the air act like you're about to do a j.4B and just barrier at the last second, it will make them waste 50 heat or it will set you up for a free fatal.
A couple more things to watch for: In the corner, Jin has a crossunder after icecar A finisher, I think its dash 2b then it's a cross under. He has a fake cross up with j.236D (old news). In CSE Jin loves going for normal grab resets during freeze, whether it's purple or green don't get exposed.
That's all I have for now, I'm sure I'll come back and edit this around the 16th after my next session.
