I think everyone will agree that it's annoying getting super 0wnage by these two attacks.

Kekkai Chakra: You know how there's always a pile of bugs on the floor? you should have it continiously eat your opponent's chakra till it's killed instead of 10 seconds delay. Have it with a lot of hp.

Kage Shibari no jutsu: you should make it so if another opponent hits you you'll lose one step, that way it makes sense, but if they do your target will get hurt aswell, so better not use a rasengan xD

Sharingan : dunno, just can't be bothered to think of one

Kanashibari no jutsu: get hurt by someone else other than the user
