Did they buff teemo?

I've started banning teemo in rank everytime but then I thought "Who actually plays him?" GUESS WHAT I went 5 games without banning teemo and he would always be picked, I would have to suffer everytime I had to solo push because he would pop out of nowhere, blind me then take half of my hp away from 3-4 darts, if I decide not to push and clear his mushroom, THIS FUCKER POPS OUT OF NOWHERE AGAIN AND SPAMS ME WITH BLIND DARTS, I FUCKING HATE TEEMO
