To be honest Lee Sin is overrated. Errr, yeah, he's not an example of balanced kit, but after the Cripple nerf, i just feel 100% fine about him.

Yasuo is overrated too. I just don't want to see him at team ranked matches. SoloQ is the place where he doesn't get as much help from the team.

And Teemo is rather annoying due to insanely nonsense gameplay. Basically all he does is rightclicking and baiting people over goddamn invisible shrooms. The feeling of getting outplayed by someone who only rightclicks is just wrong, not to mention it's just dumb to see him shooting all over again, and again, doing just nothing besides that.

Honestly never had problems with Yi. He's just doing what any ADC does, just faster and at higher risk. CC always was the answer, and always will be.

And Amumu is just strong, but definitely not uncounterable.

If you want an example of annoying champions - any ranged toplaner. Most top players will tell you how much of pain is it to be outranged hard in lane. So teto applies there too.
