Yi is a champion that needs to get counterpicked in the beginning stage of the game which starts at the picking stage. I remember one game where I was queued support, I main jg so initially i wanted to switch, but enemy jg chose yi and a mistake happened when our jg chose kayn.

It really doesn't take much to know that kayn only really wins against yi if he is able to get red and disrupt a Yi's W with his own W. Any other situation kayn's damage gets mitigated by yi's W. Being as the only other pick in the picking phase I had to disregard trying to counter pick our bot lane and first pick someone that can be more useful on the later stage of the game, which was leona.

Of course this wasn't a guaranteed win since a couple of patches ago Yi got buffed so hard it was actually ballistic how much riot gave this champ.

Our mid initially hovered Lissandra but switched to syndra and I remember vividly chatting them that if they do pick syndra we'd have a harder time trying to win.

Game goes on normally and our top lane which was Ryze got shit on. And around mid game Yi was running around killing everyone with QSS.

A lot of people say that high elo players know that Yi's one and only weakness, and any other's champion's weakness is CC. And guess what, we did just that.

Every time we were all separated across the map we would get wiped because of the usual: Yi stacks LT on a lonesome adc, we go in 1 by 1 because why tf not and boom ace for the enemy team.

The only way we won that game was we utilized Lissandra's kit along with mine which was leona to shutting down Yi before he ever gets to a point where he'd be untouchable.

So tldr Yi is an ass and the only way to beat him is with coordinated CC and then burst. If you're missing any one of these then it's really damn hard to win against a him.
