From my experience. Most people in bronze on silver, don’t have much communication at all. Most don’t even group up. Let alone group up on the point.
Not to mention, I’ve also noticed a lot of people decide not to play mercy, due to her recent nerfs. True her res isn’t as good as it once was, but she is still the most effective healer.
Also, add Gold players to the list of toxic people. I’m in Gold and have to deal with both silvers not wanting to group up or, god forbid, sit on the point. And I have to deal with toxic golds.
I agree, there are quite a few players who are wrongly ranked, but there’s not much you can do about it.
