So a few skins don't have the naruto animation. It does, however, work on Deathsworn and the base skin.
Also, the current run animation looks really wonky, I think anyone who plays Katarina can agree that it still needs some tweaking or a whole new animation?
The pbe one does not feel like it fits Katarina, Maybe Work with the hasted run (naruto run animation.) It blows any other running animation out of the water haha :P
