Not sure what is this referring to. Vacuums is what makes wind 'oppressive 1v1 single target mastery' and it is now almost never worth using in 1v1. Even in a long cc, you are probably better off just using other jutsus. Vacuums are basically an extend to stuns in teamfights and wind is imo the worst teamfighting mastery.
Nerfing Claw wouldn't kill Wind. Claw is the reason Wind started being considered OP, if you look it up, there was #Justice4Wind posts and people asking for new jutsu before Claw, and then same people wanted the mastery nerfed. Wind did not need justice, it was already strong. People trying to fix what wasn't broken got the mastery overtuned. That's what made it OP. As I said, the fact that Wind now has one of the top 5 worst jutsus in the game (imo), and is still almost as strong as before that, speaks for itself. Flicker Claw is a guaranteed damage + cancel + DoT.
Nerfing the most obviously overpowered jutsu which is literally guaranteed and locking Fan to its sub mastery (or changing nados, so they can't be abused by int Wind) was the better and, imo, obvious solution. Hell, even nerfing the damage it does or removing the stun would've been better than making it runcast. Ruining a jutsu that was not the reason for Wind to be OP did not fix anything, it just ruined a jutsu.
If someone disagrees, please explain to me, why did nobody call int Wind OP when vacuums worked the same way for YEARS and nerf posts started rolling in after Claw got added (and vacuums got overbuffed, but they were then nerfed to what they were before). People were calling Wind the weakest mastery (which it really wasn't, it just didn't have guaranteed damage) before Claw.. it isn't rocket science to figure out what made it OP.
Flicker nados and Claw are the problem with Wind.
