Why would you change Garen?
Just why? The moment that champion gets on proplay everyone at Riot starts panicking and they plan a new rework for him. He's now one of the most failed champions in this game. I used to main him. Now I both can't and don't want to. I'm already disgusted by him and he's already just a permaban. Who actually thought that the changes made to him were a good idea?
I don't care that he is countered by poke, I honestly don't. No champion should 100-0 you because they just so happened to land a silence on you. If he catches up to you it's over. You can't cc him because tenacity, you can't outrun him because of his Q and and Phage. He can build AS and tank and he will still deal enough damage to break you.
