Wind could still be used offensively; throw your opponent with enough force, and they'll be damaged by collison with whatever. Plus it could stun them, manuever them into a better positioning for you - whatever you want if you're creative enough

And if air were thrown fast enough, it could possibly cut through metal... that and even a small tornado would be very destructive lol
