I honestly feel Garen is in need of nerfs.
He's too simplistic for the rewards he brings, and he's hardly any risk in making plays with. Every champ that I know that I am against as Garen I can easily formulate how to beat them, and get relatively good success with the strategy.
Rito made his DPS numbers too high and his Ult and Villain mechanics need to be toned down a lil more. Just saying. Simple champs shouldn't be as reward as the more mechanically or strategically difficult ones.
