Simple idea for Garen's Q
Make his Q a small leap skillshot. I am talking a dash small enough to make it over small walls and that is about it. Why you ask? Well allow me a minute of your time and I tell you my reasoning.
Garen has two main problems, the first is that he has no hard crowd control (silence still lets them auto and move around) and the second is that he has no way of getting into the fight. As a Bruiser/Tank the first problem is already critical to his identity, if you can't do damage (which will happen if you have a crappy lane) then you need to focus on tankiness so you can crowd control and peel but this is an option Garen flat out doesn't have, but if he did have some sort of lockdown he would be ridiculously overpowered in lane, so what can we do about it?
The answer is simple, we focus on the second problem instead. As a front line melee fighter it is absolutely critical that you be able to get into the fight and provide for your team. All Garen has is a speed boost and that still forces him to try to bull rush into the enemy team. So here is what we do. We change the Q into a jump followed by the normal speed boost. This will allow him a small gap closer to initiate a fight or turn around without providing much else aside from chase potential. This would also stop him from being completely countered by champions with ranged harass without just having to try to charge them.
