HOW is this ACCEPTABLE by Riot??

How can this blatant abuse of the Matchmaking system be considered a-okay by Riot??

Our team had mostly Bronze and ONE silver player. Their team had 2 Diamond (Cho'Gath admitted to being a Diamond smurf) a Plat, and Annie was a smurf as well. The only one who wasn't, was Caitlin.

Naturally, we got the shit kicked out of us. That's to be expected when you put Bronzelords up against high elo players.

What's even worse is that we were treated like shit all game. Constant gloating, verbal abuse, being farmed for kills like we were bots. Have a look at the chat log in the post-game lobby.

Yes, I'm angry. But only due to the fact that the enemy team were complete and total asshats. We reported them, yes. Will anything happen to them or their accounts? Hell no.

Again: HOW CAN THIS KIND OF TREATMENT AND MMR ABUSE BE CONSIDERED ACCEPTABLE BY RIOT'S STANDARDS??
