In Regards to Teemo, as well as "no skill champions"

Teemo has been forever regarded as the most "annoying" and sometimes "overpowered" champion in the game.
In regards to contrary belief, Teemo is actually fairly....bad. Mushrooms, yeah they supply a lot of utility, but this and his Binding Shot remain the two only good things in his kit.
His w, worthless for escaping, but decent for roaming. His e, not that great in general, only good for pre level 6 poke.
Teemo is countered by a lot of champions in lane, and lategame he is very squishy. He cant even play mid due to this.
Also, most "no skill" champions aren't op either. You never see Katarina, Yi, or Yasuo being played in competitive play at all.
