I didn't know how long I'd be away, and I'm still not used to it working that way, and I don't like abandoning my team, even if I don't know them. Maybe it's just as much of an abandonment if I leave and don't come back as if I just quit, but like I said I didn't know how long I'd be, and anyway it feels worse.

: If it had consequences to quitting, then yes, it should place you
: in the lobby after a few minutes idle + end of game.

It should do that regardless.

: But that takes more computing time than simply letting you be.

It wasn't too much for Halo 3 and Reach to do it.

: In fact, less overall time than finding a new player for that roster.

I'd prefer, and I think most people would prefer, having a player that will actually play.
