Run inside it? Dude i can stand well behind a wave but if he dashes straight over my melee over my casters then he either lands next to me or close enough that he can either instantly dash ontop me or just walk up then dash because he has more movespeed as a melee vs ranged.
Cant kill or escape from Yasou?
Yasou has the kit to beat literally any mage there is aside from possibly aurelion whose ulti just hardcounters yas, And his ability to dash around directly makes it impossible to farm for many which automatically gives him constant lane priority which is very damn strong.
No projectile mage can kill him when he is good, no shorter range can escape from him aside from Ahri.
The only perk is that a number of mages have skillshots that bypass the windwall to a degree like Syndra´s Q which gives minimal functionality in teamfights.
But there is no wonder really, this champ was made to shit on ranged picks.
The only problem Yas has is the fact that jungle exists, that is the only thing, otherwise he´d almost certainly have a much higher winrate but because he is so dominant in most ranged matchups his players cant help but constantly play aggro on him which makes baiting him in for the jungle a piece of cake.
But really that doesnt make the fact that you need 2 people to beat 1 guy like 3-4 times in a row any better when he can make a comeback at almost any time,,,,,,,,seriously if he wasnt so easy to snowball off for most junglers this champ would be insane.
