A couple of things to note. Firstly, I haven't read through the entire thread, so I wont comment on the opinions or ideas of others. To the best of my knowledge, as transformations increase in 1.3, some attacks are going to be replaced with 'bigger' ones that consume more ki, such as kamehameha to chou-kamehameha. I could be wrong, but I doubt it as otherwise characters would be able to cast tens of these attacks without losing energy. I also am not sure what happened to the stamina system that was floating around, but at one point I suggested that firing a beam should leave you 'exausted' for a relatively short period where further attacks would consume more energy than normal. This would at least impose a pause between attacks that would slow things down, but I don't know if they're even considering it. One way or the other, I'm sure the team will come up with something.
