KUROURUSHI VARIANTS

due to his extremely low damage and lackluster variants, expecially on 2, here what i came up with:
2 Air variant: vertically slam down the detached limb, kinda like enhanced Yuki's 4th move garuda, but the arm will stay stuck and it will execute a downslam with shorter stun.
blokable

2 + R: instead of recalling the arm early the use will execute a slash with the detached limb, using lit like a whip before recalling it back, if hit, will inflict more injury.
cannot hit ragdoll
blockable

3 + R: instead of hitting with the cleaver, the user will become surrounded by cockroaches that will consume the injury stacks to deal more damage
can hit ragdoll

For his ult i'd move the roachnado as his primary and clones as his G + R, keeping the domain invasion where it is
