I think host game would do good with a timer. A lot of people (myself included) want to play, host say 5 games, and then get one or two slow games, you're not really paying attention to arcomage, and all of a sudden, you've got 3 games were both players are offline/AFK.
Instead, you start 5 games with a 15-minute timer. Either you get your games and you're playing actively, or you don't get to play, but you're not stuck with a bunch of offline/AFK-games.
Implementable? Thoughts?
