At the end of the day, it is true that...
People get banned more for "toxicity" then intent feeding/afk
I've been toxic at feeders, yes. but I have NEVER intentionally fed or afked in a ranked match. You just... dont do that. If Riot finds someone who builds, idk, 6 boots in a ranked match, that person should be AT LEAST 2 week banned, and not the person who got pissed at them
