Actually, no, I've put most of my points into ki supers but I find the funnest way to play the game is to use regular melee combos to build up ki and then, when you're out of stamina, blow all your ki on super saiyan and continue to melee but throw in more supers and finish with ultras. Much more amusing than just powering up and spamming ultras.
Btw, you've got a lot of really great screenshots and characters! I've only recently started to do a lot of screenshots and videos, trying to get good angles and interesting scenes. I really wish you could disable the hud in this game.
