Lets say you are using the currently most broken possible ninja there is for arena (shisui) so i am not surprised at all. They should utterly nerf shisui basic stats because he is too strong for arena. That said if he used azure fang instead of breeze dancer you would have lost since azure fang is not made of paper tissue as breeze dancer is and would have healed everything and added serious additional damage (dance of impetus with kurama and tobirama is useless since they reduce cd by themselves.
