I think it's always been Tai/Nin mix, neutral. I remember it being like that for the last few months I've been using him.

I don't see why it would be lightning, to be honest, he's using the Susano'o, which...is kinda an energy manifestation? If it were something like Chidori-Brand stuff, Kirin, something that utilizes lightning, then it would be lightning, but he's just mainly using the Susano'o, which isn't really lightning.

I'm assuming you mean Susano'o Sasuke, and not Suit Sasuke.
