COD did fine in past games, so they can return it to those settings in general,
and in getting rid of immature players on all scales would require much more micro managing from treyarch and the report tool.. people would talk so much trash if they knew they couldnt get away with it
Hardcore is a prime example of what I'm talking about. HC is for mature players (granted an immature portion of the community still journeys there). Core is where all the little kids are mostly and where the mature players tend to skip because they dont want to play against QSers and spammers.
Also note that I mention immature and little kids in different breathes. While they tend to be the same I think at the same time you they are different groups. Little kids can be mature just as much as adults can be immature.
I remember the 80's, well most of them, some years are still a little hazy, not sure if its the alcohol consumed back then or old age...
Leg warmers, Miami Vice white suits, shoulder pads, big hair......and proper pop music...lol
