Skuzzy,
When I first tried the CT, numbers were still low, but the quality of the players was generally good (in terms of civility). Haven't been in the CT for awhile, but last few times there did seem to be less civil behavior, and more consistent gang-banging.
Although this behavior wasn't to my taste, it wasn't totally outrageous, so I didn't bother with screen shots.
The suggestion that this change for the worse is a "squad" thing is interesting and plausible. This could explain the gang-banging, and the attitude that anyone outside the group (squad) is fair game for uncivil treatment.
