the only way I'd join a short duration boot game *under 5 minutes* is if i knew the people either from places other then WL, or if I knew the person wasn't the type to boot immediately.
I Personally prefer to be beaten utterly before surrendering, as is visible on my profile i had one game where i forced them to knock me below 100/turn before i would let myself surrender, even though it had turned into a 4v1 by that time, and if possible, I don't surrender unless my team is beaten.
I haven't had any experience with 'Emperor' yet, but if all he does is troll 1 minute games, i doubt i ever will.
