Humans are fine as is, but Namekians should have their Full Power removed/replaced with Healing. Have it where you change the mode to a Healing instead of Giant and after charging your racial skill instead of transforming it takes 50% of your remaining ki and converts that amount into HP.
I don’t know about removing full release as that might upset the balance of things, maybe if we had namekian fusion to replace it but not just healing on its own…. I do like the idea for healing overall and it is long overdue.
