dont play garen, play ashe. just get 21/9/0 with a doran blade at level 1. if you steal the buff from your jungler you can tell your mid lane to fight their mid lane. then you come in with a volley and critical attack to get first blood. ashe is so much better than garen.
Errr, what? If he wanted to play Ashe he'd be asking about her.
Build BC and stack health. Defensive items as needed. His build is a bit simpler than it used to be.
