Windower gives an unfair advantage to those that play the game, straight and simple. That is against the ToS. Saying that Windower is harmless would be a lie, it's advantages in macros, recast, distance, all are distinct advantages in the game, and it's not meant to be played like that.

SE considers Windower illegal and will punish those caught with it. The fact that it can't be traced easily is the only reason they haven't banned for it yet. Get out now before we come across another Salvage incident.
