If that would happen they’d have to rebalance alot of characters. Strike bois would have a big advantage over hold men like BayGuy and Leonard who have the big dick damage advanced holds that require 9 inputs.
Regular holds costing meter...? Well as fast as it builds up currently, I think that's not a bad idea. We would see less people spamming them mindlessly in hopes to get a bite.
We would see more low punishes as well, because if someone wakes-up and you don't have enough meter to hold... you're doing something else.
