NEW SUGGESTION - Personally i think you need to better the sniping system, the scoping is very odd even though unique, the scope could be bigger and fov less on it so u can see more, when you scope in, you have to wait like 3 seconds to shoot, i think that's pretty unfair, please people thumbs this up if you agree!
GREAT IDEA, please make a friend system which you can add people ingame and in the menu, where you can message them, invite them to games, or join their game. Also with clans, you should add clan shoutouts, that appear when you log on, and more advanced clan wars things like something that reminds you where and when you're having the battle.
Some things to improve this game, first i want to start off with a minor bug, Scar-l HAMMR optics says 70 headshots but you're supposed to get longshots. The tasks are waaay too difficult, and like wilfighter812 said, after 5 days, rotate a contract, it's seriously unfair that i have to get 5 ragekills on a map where whenever i get on, everyone is a 40+ with a p90 that recks my low level weapons, i'm a good player but i can't manage that. Some people have like 20 prokills, SERIOUSLY? Improve these or remove killstreak tasks, a recommendation. Some w-tasks aren't worth doing when you put the stat change at -2 recoil -5 damage -3 mobility, how does that even help, srs. Please fix your game and we will all be that much more satisfied with it.
