Garen needs to lose his silence in place of something else, like a slow

I know at higher Elo he's not that fantastic, but in lower elo he has a disturbingly high capability of stomping people without actually needing to think of how he fights. The sustain from his passive, as well as the silence from his Q gives him extreme bully potential and staying power, allowing him to stay in lane even against hard matchups.

Couple that with his absurdingly high base damages and easy cleaver procs, he becomes nearly impossible to deal with for several champions while being a gigantic ball of defensive stats that can still 100-0 you during his silence.

For the sake of him and his opponents, add more counter play and please for the love of god add more complexity to his kit so he isn't just a one trick pony.
