That's a great post. Thank you very much for the effort and for putting that much time and energy into it.
I read everything, didn't fully understand all of it, but I'll pass this on to the team.
We discussed the ladder/matchmaking "issue" just before Christmas. We have some ideas and a long-term plan (= not this year) about making the ladder fairer and more enjoyable. This won't be soon but know that we're aware.
Reported, thanks
