Give fist kick 5 more damage and remove the start up on block and he'll be perfect
Hear me out
An iron fist 3-4-5 kick primary combo does 270 damage if he gets one more then he'd have good 275 hp combo. This would encourage more kicks to try and kill as your kick will actually do something. (You can give him kick reset on kill if you want)
Also why does the block have a start up. Why not make it instant
