Personally I'll back out of lobbies when people struggle to maintain a somewhat average K/D or they don't play objective at all.  I end up in tons of lobbies where people will go 1-20, which in all reality is basically boosting the enemy team.  When I'm hopping on flags and I have teammates dying so much giving them Pavelows and high killstreaks all the time or they just sit in the back of the map doing nothing, never hopping on a flag in domination I see that as a perfectly good reason to back out.  I even have games of Domination that I win and players will only have 500 score, people need to understand that they have to play the objective if they're going to be in an objective playlist.  I don't expect a ton from my solo domination games I play, but it'd be nice to get a team of people that even somewhat understand what they're doing.

And to prove my point, I finally get into a lobby that is decent, and am 14-10, then the game freezes, host migration, wait, wait, wait, wait...game ended "Server connection timed out". Awesome.

I don't see why you dashboard. If you go 14-10 and get mad when the server connection times out, what would staying in a game that already started or lags do? It is not like you can overrun a lobby and get a good w/l or KD ratio going 14-10 in a decent lobby.
