@thetruepilliger in general I agree w @b4njAx on this. I'm probably actually on the other side of him a little. I like a number of your ideas, but imo all of them together is too big a nerf. Which of your ideas to pick really depends on what you want Makutu to be in the end. For me, Makutu should be a defensive disruptor, so I really only see two problems with him: (1) the cheese, and (2) the insane damage. I tend to think his abilities (uppercut, leggit) wouldn't feel as broken if he wasn't disrupting and then punishing you on top of the disruption. He should only be able to do one or the other (imo, disrupting but not punishing). Problem w uppercut is not just that it stuns. W the right combo, it basically takes a number of fighters out of the fight. THAT'S what it shouldn't do, imo.
Aside from the cheese fix, I favor one simple nerf: significantly reduce base damage for regular combo sequence attacks and barge. Makutu should not be able to 1v1 absolutely anyone, as you said. Picking Makutu should mean you're choosing to be a utility tank who peels, disrupts, and helps sustain, but still has to rely on your DPS to do some actual work after you peel and disrupt for them. Switching to huaki with buffs and damage mods should make you do decent damage, not be a god. I don't know the exact right number for the damage value nerf, but it should be sizeable.
