I just won a pantheon game like 25 or 30 minutes ago on cataract domination. We totally owned the other team i had 17 kills(whole enemy team had 2 together ..) got several achievments, 190 points for game and 100 or 200 more for the achievments and the stats record me as having lost it with 0 favor points ...
I can provide a screenshot or you can ask other ppl from the game but this is seriously f*** up 
You can compare the screenshot to what the stats show lol
