Does this happen to anyone else?

As you're playing ranked, you start to build up a losing streak. Some teammates are feeding, the team wont cooperate, you get auto filled, or your team simply gets run over.

So you change to norms cuz you dont want to lose any more LP. And then suddenly you start winning games, back to back. Your teammates are cooperating, every lane is won, etc.

I'm not making any claims, but its really quite strange how swapping from ranked to norms makes such a difference in your teammates.
