I played duoq and my game crashed. I lost 48 rating from 1536 to 1488. Why? :((((((((((((((((((((((((((((((((((((((((((((((((( (((((((((((((((((((((((((((((((((((
is that bug? or is that penalty from crashing/leaving???

From what I gather with the limited information you provided is that You entered into the 2's game then lost connection. If that's correct, you're partner probably lost resulting in the team loss, and since you were in the game at the start you suffer the personal mmr drop along with the team rating. It's nothing new when it comes to arena games. Working as intended.
