Mmr is based heavily on levels, the tutorials give achievements which give xp which gives a few levels, done.
If that's true then way to flip flop on the idea that levels don't matter. Besides match count and average win rate % is a much better metric.
I mean yeah... vets get screwed over by noobs alot and stackers always get highest win rate (but thats what udog was for-to render wins by such unfair match ups meaningless).
Plus udog, nov wins and other marks of actual skill should drastically contribute to mmr (ignoring achieves like the class and map ones because of their arbitrary nature).
Something besides the clearly flawed lvling system needs to reflect mmr more.
ALSO MAKE MMR CLEARLY VISIBLE. Like have mmr on your profile. It has always come off that muse hiding the numbers was them showing lack of confidence in the system itself.
