I've tried having people gank him but it just doesn't happen, and every single game I've played since the patch has had a Teemo top. Every. Single. One.
So far I've faced him top as Shen, Irelia, Diana (yes, played her out of position just to deal with this), Pantheon, Garen, Darius, Mundo, Malphite.
My last game against him was with Diana and everything was okay for a while, landing my Q a lot and my shield was taking most of the damage from his AA. My jungler never visited top once. At level 4 the enemy teams jungler came up (Darius) and they destroyed me. I say to my jungler "Fancy coming up? He's gonna get too far ahead if he's not shut down now"
Junglers reply "No way, he's ungankable" The fuck am I supposed to do about that?
