Bummer bro... when you join a game say really quick that you've been host exploited all your games so they don't kick you.  However, you should try joining "noob" or beginner games, or host your own that say noob or casual, will balance, something like that.  The state of this game is that a newer player has a very hard time allowing his team to stay competitive against people who know how to play... or at least what demigods combos are best to play.

I may be wrong, but I believe that if a player unplugs their internet (physically) it causes the game to Desync, so no win or loss for anyone. Ending, conceding or ctrl-alt-del give the game time to register that you've quit, but if you just unplug, it doesn't know what to do. I think if the host does it, he gets a win, and everyone else a loss, or nothing.

Like I said, I may be wrong, but that is how I understand it. I hope I'm not giving any pointers to junior-douche-bags out there, but I think that anyone out there who is a loser enough to pull this crap already knows how.
