I was watching Kross on stream yesterday and he was saying something that I 100% agree with, and that was that kids play CoD as they think it's cool, and when people get older and think the game is for kids they move on the the more tactical and slower paced BF games, that's spot on.
Drift0r even mentions that half of the community love sniping and quickscoping, that's because that half of the community are the young teens with ADHD who like to brag about there cross map 1080 no scope that they once hit jumping off a building, that is the community the are aiming (no pun intended) to please here.
