I don’t think it should cost more bars but I do think the bar you used on it should take at least twice the time it takes to regen rn.
It comes back way too fast imo. I believe whoever makes the right read should be rewarded but sometimes I read a wakeup roll, punish it, then I read another one, punish it and when I look at their meter they already have another one on deck and I have to guess again in very short period of time.
They should also change the command to execute them and the window to do so bc I’m tired of getting random stance changes or nothing at all when I input it.
Another thing that is a must at the current state is a major major U2 buff. All U2s should have ridiculously high hitboxes. The way they are rn is terrible, you will lose to jump ins 80% of the times bc they don’t reach high enough even when you make the read I don’t really mind them losing to crossups (even tho I feel like they should either auto-correct better or have a little bit better hitbox behind directly above you) but it its so bad when you know someone is gonna neutral jum meaty you and you go for a U2 only for it to whiff and get you punished. They should completely deny and delete jumps in a certain area.
The meter cost and regen should be balanced accordingly, something like:
U3s cost one of each bar. The offensive bar comes back at normal rate but the defensive one takes 7 seconds.
U2s cost one of each bar but since ir gives you a full combo both bars take 10 seconds to recharge.
Foward roll allows you to put the opponent in a very shitty situation. Costs one bar but the bar takes 12 seconds to come back.
Back rolls are basically a punishable tech roll (I also think they should recover faster than foward roll) that can get you out of pressure sometimes so they cost one bar that takes 7 seconds to come back.
