Galio is overpowered
His E hitbox is broken (as in, it'll go over your head and hit you), and his Q is too reliable with too low a cooldown for it's massive damage.
I mean, giving someone an ability that can oneshot minions when barely building offensive stats and without any sort of extra damage to minions is bound to be broken. Not to mention Galio's Q ticks way too quickly, as if it hits you, the size of the tornado means you instantly take a tick of damage. I mean why not just add that into the initial damage? It's unavoidable anyway. Not to mention the sides of the Q hurt way too much as well (I mean, why does Galio's Q even have sides? Just the circle and DoT is plenty), because of how large they are.
Other than that he's fine. But Q needs a bigger cooldown or less damage + bonus damage to minions (so he can still waveclear) and tick slower or smaller tornado.
Oh, and I'm not salty because I lost to a Galio. I just fought one, he fed his ass out but still would've 1v1'd me easy if he could hit his E's/Q's, and that time he hit 2 Q's for 300 damage each, he forced me to back.
