Can you do team Gohan (kid, teen, adult, future, majestic) vs team Piccolo (king, early, end, Naaaaaail, maybe add king piccolo's servant just to make it 5v5)
No one cares. It’s all personal preference. You’re not winning any awards by thinking either one is better than the other. And you’re not changing any minds. Just move on.
Maybe. In xenoverse you do have to fill up one special move slot just to go ssj though. In this one, you can just do that, then gain an entire new move set. Especially with Goku. Goku therefore has moves for days see? Besides, I like starting base with Goku, and working all the way up to ssj3. That's my 2¢ anyway. Xenoverse is cool though.
