Yasuo has always been the permaban meme in gold and below. He has 50 flashes and 100 % crit with 2 items and with what he builds now, a lot of shielding and can basically block auto attacks from an adc. Yi has ways caused people problem in low elo too. They actually introduced counterplay where his q has a cast animation now. But of he gets it off, you cant cc him. The tradeoff is it works more like juggernaut's ultimate from dota 2/fiora's old ultimate. He is also the ultimate pentakill meme champion. Which would you rather paly against.
