What is considered boosting?
So, I fought a yi around a week ago, and noticed he had 100% winrate at 40 matches, and had a TF winrate of 3%. He's a bronzie, and seems to queue with someone who by extention has an evenly high winrate. Looked the main guy up today. 90 MATCHES and 100% winrate on Yi, 6% on TF with 48 matches.
If I've ever seen a carry booster, I'd put my money on this one. But is Riot's judgement on it based on trends or they need to have concrete evidence like chat logs stating that there is a carry happening to discipline people like this? I'm just surprised that after a week, and surely other reports, that he's still at it.
Even if he's not carrying, he's not making it fair for the ELO he's in by keeping himself there. That alone should be enough to be disciplined, imo. What does Riot think of this situation?
