Can we address the seriousness of how broken this build is?
This was on a Master Yi. He had ~3k health, and did SO MUCH DAMAGE for the build he had. He shouldn't have been able to do roughly 2k damage with a Q and a couple of basic attacks, and he said, "but im squishy and can be killed easily by CC". Really? Is "squishy" supposed to be 3,000 health? Should a semi-tank - who's able to heal himself AND do true damage - be able to do 2,000 damage by pressing Q, right-clicking, and letting AA do all the work for you?
We need answers, Riot.

and a
as AD items and went full tank no boots(50:00mins), still one shot everyone. Sated devourer is a strong item but it isn't op, the issue isn't with builds, its how players get it so early. Late game when everyone has their items the Yi would probably get stomped on.
