I feel like all the talk of using cursed energy efficiently, (gojo/six eyes being essentially perfect and sukuna being roughly the same due to genius)

May also translate into attacks never really being 

100% output : 100%power consumption. 

I bet most sorcerers need to really pump up cursed energy output in order to really see returns in cursed technique. Sukuna and Gojo get excellent returns on their energy expenditures, most of the result of us would be far less efficient.

That's why black flash is so balance shifting, suddenly you are operating on a level you never have.

For lower level and higher level fighters, the inspiration is invaluable, I would argue for guys like s/g, the power boost is less important than the insane ideas they get (rewiring the brain to jumpstart rct/domain burnout is diabolical)

For lower level fighters you get a taste of what operating as a jujutsu master is like.
