The thing that triggered me to make this thread at this moment was because I just had a game where the Lee Sin decided to AFK because the game is lost though not completely. This is due to the unfairness of Kassadin and his hyper-scaling potential on Dominion. Is it correct for the Lee Sin to AFK and making his teammates suffer? The answer is no but if this problem persists, it may become problematic.
Even though I say report Kassadin at the end of the game, I for one have only reported the Kassadin twice for unskilled just to relieve my anger. For anyone who thinks I actually report them, it is hilarious because I know how the tribunal works and how Riot handles false reporting. Even if I were to report every single Kassadin "spammer", I highly doubt it would make my reports null because there just aren't enough of them to justify the reporting. Not sure if reporting someone for unskilled even goes towards false reporting because unskilled reports doesn't seem to do anything for the majority. If it lowered their elo, that is great!
