i know who you're referencing, and some of the guys in there are good fights. most of them tend to ho, run to the gang or ack, or just run away if they're alone. it's ashame, 'cause that squad used to be pretty cool.....till the bottom feeders started joining. 
Ho'ing, running to squaddies or ack, or just running, is simply a part of the mechanics of human behavior when in a win or lose fight and I have zero problem with that. No whining!
The thing about the bottom feeders is a valid observation until you actually play the game with them instead of against them. To a T they are all fun to play the game with. I used to hate that LW squad in MW because I always ended up butting heads with them in chat. Once you switch sides and play "with" them they are just like everyone else, good people.
In all my years playing MMOs I have encountered only one person that was truly a terrible individual, someone I suspect is either dead today, incarcerated, or institutionalized. I know he is no longer in THIS game.
