Your right that Goku is going to have a step up on Vegitta with his new moves though. Allthough Vegitta and Goku are both balanced for different purposes Vegitta usually has the more powerful blasts. Vegitta had the big light shows and goku teleported around them. If you truely wanted to balance vegitta with goku as they were in the series vegitta would gain a large ki blast. No charge, a bit slower the a normal ki blast, bigger, lots of damage, and very large ki consumption. It has been done lots of times during the series. Allthough this would balance vegitta and goku it would leave the other characters in the game in the dust most likely so I don't think I myself would do something like that. Furthermore I support the mod makers 100% in the way they go about their business. I would do it the same way they are and there not making any money. Plus if they were to try and please everyone who wanted something changed it would turn into counter strike and who wants that?
