I understand hosts who quit, depending on the reasons, but bad sportsmanship does make me feel pitty for the bastards quitting.
I have even experienced that the host quit the game due to "WRONG" team building ! This really sucked as you hang out in the lobby for some time just to make a missed game.
When this is sad I must admit that I myself have been the reason for lost games for some. Being a parent for some 3 and 5 years old, not all evenings are quiet and they need attention during a dogfight
In flying mode I practice to just keep my plane flying by itself, being an easy prey and leave the game running. If in lobby, as creator, I choose to quit instead of leaving fellow flyers hanging in the lobby for whenever I return.
This just to say sorry, and to make you guys see more reasons for why things may happen.
