Stats are not just awful.
On one of their last patch they removed the option to view player statistic duel based on played maps. For instance, stats used to be kinda:
duel 666
dm6 333 wins 0, losses 333
t4 333 wins 0, losses all, u loser
I had about 60% of the matches played on dm6, so I wanted to play more t4 to balance the number of played matches and the general skill. Now, I will just have to blindly play till 'most played map' field will show vertical vengeance instead campground redux.
It just removed a little bit my motivation, already.
