Ninja is unfun and has too many issues, please address.

For of all, any action/spell force you to choose between offense and defense is not a good action/spell
Bushin is only the end result of tune down PvP system for casual playing.
Also, Bushin sync best with ambush, defense reduction only good for 3s when you stuck in the ambush animation.
The real defense reduction is from doton, but that is laughable for a meele compares to DRG, SAM, RPR, and Reaper.

How is doton going to help when now Ranges domnate both Frontline and Crystal Conflict?
I also prefer one controllable stun rather 2 consecutive stuns when most of time 2nd stun usually useless because of Purify
Beside, i think it is fair to ask Shukuchi ts function as what tooltip describes

Range dominate in CC? What is this timeline you're playing in? I want in...
