It could be a couple of friends just getting bored of their preferred game mode and come on to HCKC and are either really new or are just on there to screw around. This game feels like it has the player base and player mentality that most Call of Duty games have 8-9 months into it's life cycle. This game just got to this state a lot sooner than most Call of Duty games and I guess a lot of players just don't give a flying sponge about the game anymore.
I have to ask have you tried hcdom ?
For me that is where I have found the most people that seem to forget that there is an objective.
A majority of my time is on hctdm.
good luck with finding better randoms and have yourself a good one.
