usually, when I come to the conclusion that a game is lost, I give up (gg, ctrl+k). I sometimes get the impression that this behaviour is not appreciated very much. Of course, I could just walk afk, go for a smoke and then come back to the finished game. However, it seems to me that walking afk is no less rude than giving up^^ and additionally, since I am married, my gaming time is kind of precious and I don't want to waste it just like that. Interestingly, on other strategy games (like..say chess) imho it is considered bad practice to continue a game that is clearly lost and thus forcing your superior opponent to waste his time with finishing you...
What is your opinion on that matter?
PS: I mostly play 1v1 rated games
