Nerf him, he is able to combo into any state easily. He also able to summon 2 ninja for extra damage/shield depend on the situation. Dont even get me started on his mystery skill which causes fire damage and knockdown. I'm wind main and I dont like fire tbh.
If u can manage to get him into 5 star, he will be more OP than Tobi.

P.S. is the server live now?
