Let me list some off
1: Mountable mini dinosaurs
2: Two energy attacks can collide and whover taps, clicks etc. wins, if it is equal it jsut explodes
3: Flying battles
In the scene where they become super, they are holding eachothers shoulders, trying to push one another, something similar should be implemented
6: Dark Nimbus?
7: Senzu beans
8: Being able to vanish/go at an extreme speed
9: After image technique?
10: Saiyan race, I know many people may have asked this, but it is much like human, only with a tail, and has only 2 levels Super, Ultra Super saiyan ((Super Vegeta, Trunks when he was buff and fought Cell)) and Normal Super Saiyan, beyond that is too overpowered
11: Hyperbolic Time chamber area
12: RP as in Roleplay for people who enjoy that stuff
13: And finally, an actual annual world tournament, where other players are in an actual bracket and are matched against eachother, and other players can watch two players duke it out with a spectate mode. It can happen ever so often, unannounced or every few days or weeks
So those were my ideas, what do you think?
