I also had a couple of issues when leaving custom games early and then trying to queue. It tells me I am still ingame. Refafing fixes that but in combination with the tmm ui not loading 1/2 of the time this problem is annoying.
Also soloqueue also displays global rating ingame. I think a couple of people were more afraid of me than they had to be
Also the rating dependent map selection seems to be working a bit weird. I suppose it works by the shown 2v2 rating (ยต-3*sigma). For instance I got canis multiple times despite being very far from 1800 rated. Also avrg of all players was far from 1800. Now the question is did I understand smth wrong, did Brutus get a wrong list or maybe made a mistake when entering the maps into the system or is there an error in the code?
But so far it has been a nice experience.
