Change to matchmaking

So lately it seems that many times I join a Queue I end up regretting it because players flame each-other in lobby , threaten to troll or only speak french which I don't understand.

In those cases I have a choice: Either stay and lose the game and lose MMR which technically ensures that I stay amongst the community of low MMR trolls or get punished by the system.

In other words: -If I lose I get punished -If I leave I get punished

• I have no chance to win solo with a team that intentionally feed and has no teamwork

There is no punishment for players who grief and there is no punishment for players who refuse to communicate with the team so why is there a punishment for players who do not want to play with griefers and none-communicative bad players?
