think about that for a second. they're played every game, but their biggest counters aren't. what do you think that says about the state of balance for them?
Lee Sin is the most popular non-bot champion, and is good at killing ADCs.
This is followed by Yasuo, who is good at killing ADCs (as you mentioned).
Next is Ahri, who assassinates ADCs easily.
Then Zed. Then Riven.
Lux is the first champion on the list who isn't at least partly an assassin. And she's followed by Mister Yi, Irelia, and Xin Zhao.
Anti-ADCs are played all the time, even if they aren't assassins. Malphite is an anti-ADC tank and is one of the most popular tanks in the game (maybe the most). Hell, Garen's job in team fights is more or less to be an assassin for the enemy ADC or mid laner.
