Well then they should add 2 or more types of powering up..otherwise it would annoy when see after every powerup your screeen shaking..
Aura-powerup:slow powerup,able to move
[POSSIBLE ANIMATION]: just seeing aura-charge just like the show, lightningsparks
current powerup:fast recharging
[ANIMATION]: same animation
powered-powerup: extremely rapidly charge (only for stage2 or 3, SSJ2 or SSJ3)
[ POSSIBLE ANIMATION]: lot's of wind, lightning, ground shaking, highwaves on water,rocks flying,lightningsparks..
unable to move ofcourse
I also think that powered-powerup should work best for those high stages 3e stages
Then normal powerup should take longer and powered-powerup should compansate that...
Cool if could be used once in 30/60 sec..should be able to charge max 60 sec..
That would be cool
