Taijutsu as is kinda unfun to play against with your opponent just opening gates and spam pressing a to teleport to you and do 1k punches and on crits like 3-4k punches. So here is my suggestion for a taijutsu overhaul
Fist of Nirvana- Instead of making it just a punch you do close range, maybe change it to work like chidori or rasengan and if you miss it deactivates. Feel like it would see more use this way
Leaf Gale- Just need to be fixed since it does not work already left a post about it in bug forums
Front Lotus- As it is it only does slightly more damage then lion combo but comes at the cost of 25 wounds if it lands. Maybe buff the damage a tad bit
Shadow of the dancing leaf- As it is shadow of the dancing leaf is a toggle with no negative and can stay on forever. Either make it have a timer so it can only be one for a brief amount of time ()20-30 seconds maybe) or make it so it takes up a part of the users chakra pool until it is toggled off.
Morning Peacock- Supposed to be one of the big payoffs of opening the 6th gate but is never used by anyone. I think this ability either needs a big buff to damage and to the size of explosions for it to be worth using, or my preferred change would be to make it a toggle (similar to my suggestion above about shadow of the dancing leaf) that makes punches have a dot like hosenka or coiling flame does.
If these changes are done however, regular punches need to be nerfed. Either nerf the damage of punches outright, or do it in conjunction with a nerf to the crit passive in the strength tree.
