I just won my last game but the MMR didn't changed. There were no leavers or some issues to make this happend.
It's the second game this week and I'm quite mad because both of them were wins and I didn't received any mmr.

PS: it was a really bard game with antigamer in team and we managed to win so that's why in insisting for 25 mmr.
