He needs a buff. He seriously, needs a buff. Goku and Vegeta being some of the best fighters in the entire game makes as much sense as cheese in macaroni. But when Rage Future Trunks is stronger than Gohan, and the most viable way to use Gohan for the main story is to fuse him with Buu, when Buutenks is just as strong, it feels like such a slap in the nuts to the original half breed Saiyan. Now, I have no idea when or if this game will be getting updates at all, but we need Gohan Beast. Evolved from Super Saiyan Blue, get rid of his god forms entirely, whatever must be done.
Also, side note, he should keep his purple Gi in his normal colors, and his shiny should be the orange. But that's just my opinion. :)
