A system that allows you to transform faster the stronger you get say you have 80+ in every stat you can transform instantly or say you only have 10 in each stat it takes a longer time to transform
i already talked about this once
i personally think it should work like this:
you take the ki that would be drained when you transform into ssj/ssj2(you should be able to instant transform into a ssj3) and multiplie by 3
and then when you use that instant transformation it basically takes up that much ki
