I'm not gonna lie, alot of the battles in the game pretty much play the same.
What I suggest is that you always use a rushing charge attack to break your opponent's defense then follow up with the combo of your choice, preferably one that leads into a pursuit attack for extra damage.
Also, use your Ki blasts as much as possible. Don't charge it, just spam it. It's a good way to string combos together since it leaves the opponent defenseless.
And get good with signatures, they reduce stiffness time drastically and allow for more versatile combos.
Good luck !
