Main changes this game brings: Somewhat sped up jumps, ability to cancel normals into other normals (possibly into ex special moves?), withdrawal of focus attack system, ability to tech roll on knockdown.
There’s many more changes and feel free to list them in your analysis.
One thing I can say is that the removal of the focus attack system should be highly beneficial to characters who were weak against it. Chun li comes to mind. Unless they change her frame stats for hazanshu, I see it as being a relatively safe and spammable way to get in and mix up people. My prediction is she could be very strong in this game.
The ability to tech roll hurts a lot of characters whose main strategy was wakeup shenanigans. I don’t see cammy and akuma (assuming he’s in) being as good in this game, unless significant frame changes have been made to them ofcourse.
Edit: Maybe akuma won’t be hurt as much since most of his shenanigans lead to untechable knockdowns anyways. I don’t think you can roll on an untechable knockdown.
