Dota 2

I have almost 11k behavior score(I reached this week) and low MMR, and in my last 8 games all of them I have a 0/5 on my team by minute 6-7, I can gank their lanes, give kills, they just lose it anyway. It is also common, almost every game, to someone actively grief like sup 4 abandoning the lane early minutes and refusing to participate in fights as well.

I'm confused cause after the first behavior score update my games felt a little better but something between the compendium patch or the fact I reached almost 11k on BS feel wrong, it is a lot worse than before the behavior update.

Anyone with high behavior score is feeling something related?
