I noticed a bug a long ago but never bothered to post it or something, but there is a bug in the career profile. You can have more lost+won games than total played.
An empty loss is added to your profile when u play a game and you get disconnected even if you can reconnect to the game the loss still counts on the profile stats.
For example - I have played my DPS placements and got disconnected in one game, when I have finished my placements 4Wins and 1Loss in my career profile a total of 6 games appeared and 4Wins and 2 lost games even tough I just played only 5 games
