I know you tried, but Master Yi is way to strong.
So i went into a blind game, playing evelynn in the jungle no probelm. Vi their jungler and a Master Yi as their mid laner (ours was Diana). Everything is going fine i get 3 kills early (one on Yi) and i thought we were in the clear right? No, Yi roams bot lane had only gotten 1 kill that entire game had maybe 80 farm at 12 minutes, 1v3s myself,twitch and Janna with no problem. What did he have? a Black clever.
Now from then on he proceeded to completely carry the game on his own with just a Black clever and Bloodthurster. Completely deletes Cho'Gath(a tank) 1v5s our entire team no matter what we try to do. Now i don't know but i'm pretty sure you call OP on that because i'v never seen a fed Yi do that, let alone one that hadn't got but 1 kill.
or more AD.
