Interesting, Teemo neither seems to be played nor hated to the extent he use to.
He use to be everywhere. Hated by enemies because of his deadly mushrooms. Hated by his teammates because half the teemos didn't seem to know how to do anything useflul other than just place mushrooms.
But that meme seems to be dead, killed by all the changes to mushrooms. They are no longer a terror, merely an annoyance that prevents you from chasing down teemo. They might occasionally kill you while low, but usually the damage is shrugged off. Tanks are known to just run through your entire territory with the goal of taking out as many mushrooms as they can by running into them, knowing they will likely only tickle - even if teemo is max AP.
