Well, you can still go into dolphin loops; they gave her moves less untechable so if your dolphin doesn't hit in the right position, you're most likely going to drop that loop (unless your frc). CH j.H is no longer fully untechable so it's not as free anymore. If you hit a CH j.H too high up, you won't get a loop. You can do stupid stuff with j.623S though since it can now lead into knockdowns--if you know how to use it lol.
