Perhaps something else that could change with Turtle Hermits is have Super/Giant Kamehameha go in a straight line like Super did in 55 cap. They would, however, keep the width from the AoE versions (10m for Super and 15m for Giant). This could allow players to get out of its range before it's fired while allowing the skills to hit more targets. It'd also stay more true to the fact that these skills are beams and not ki spheres like Big Bang Attack. Final Flash follows this example as it has a 15m length and travels in a straight line.
Speaking of Final Flash, it needs to switch places with BBA in both power and skill tree. Having Final Flash also calculate damage from your Sub-Weapon would be nice as well.
...at least that's how I think it could be. Anyone else have any thoughts on this?
