He already hard counters mages with an ability to deny all their burst. He does not need to be buffed towards them.
Edit: just to bring a little clarity to my point, im not talking about ONLY his windwall to a mage. His entire kit is incredibly toxic. He can clear early waves in about 8-10 seconds (which is way faster than anyone else) which will force the wave under tower, and a mage is gaurunteed to lose a lot of cs. He can use his E to dodge all their skillshots (most mages rely on them) and if he slips up once? "Face the Wind!".
