I see Lee Sin or Yasuo in every game and I'm bored of it
Before you start telling me "Oh, those champs have pretty easy counterplay," I know. I don't typically complain about things, but I see either Lee Sin and Yasuo picked in literally 100% of my games, and I'm incredibly bored with the game as a whole right now because of it.
They aren't OP - not by a long shot. They have they're strengths and weaknesses, and for both of them it's pretty obvious. Yasuo is melee, stay out of range of him and dodge his knockup and you'll pretty much just kill him. CC absolutely destroys him easily. Lee Sin is only really strong in the early game and falls off very hard in the late game - if he doesn't get his lanes or himself snowballing early, he's basically useless for the whole game.
My biggest problem is how often they're picked. I wouldn't be opposed to nerfing them just to have their pick rates drop, but I know that nerfing them to lower a high pick rate is unnecessary. Buffing someone else up so that they can attract some of the people playing them could be a good idea, but again probably not the best idea. Honestly, I can't think of anything that would get their pick rates lowered effectively short of an entire meta shift.
The plain and simple fact of the matter, at this point, I have been seeing one or both of them picked near 100% of the time in the past several weeks, and I'm incredibly bored with playing with/against them.

. And where are the
players? Where are my fellow
mains? I haven't been playing as Corki in awhile but I haven't seen other Corki players either. He's a powerful champion, too so he should be a convenient marksman to play as.
