Awright I did it. I host quit at the end of the match. Intentionally.
I wound up hosting a Black Box game. After a few games this player BuMoose (or something like that) showed up. Level 55. Masterson and proxies, oh my.
It was me (level 35), a couple of other low-30 players, and everyone else on lower levels. Bu was always on the "other" team, and most of those games he was on MI6.
This goes on for at least six games. My team wasn't the greatest, but with a guy hosing down the crowd with a Masterson and laying proxies it was pretty much hopeless. We weren't even close.
I'm not saying s/he shouldn't be playing, but when you show up and your whole team is riding on your back it stops being a game.
I was hoping Bu would get a clue and leave, but they didn't. So.... I shut it off.
Sorry to any other players who I yanked the plug on.
