What a great matchmaking system you have there Riot!
Just because you put a Riot employee in there doesn't make it any less of a completely r%%%%%ed idea to match a challenger 1 player against unranked/gold players. There's absolutely no situation in which this is acceptable.
Guess what happened, the challenger completely destroyed everyone. What a surprise. Yes, mad, yes bad, but then again, so are 99% of the player base compared to that Zed.
Yes, I already know, there are separate matchmaking for ranked and normals, but no, it's not an excuse, put some consideration in the system.
P.S Congratulation on laugh spamming the whole game.
