Some stuff you should add: The weapons should be unlocked at every level (like 1 per level) instead of 10 at a time every tenth level.
You should also add contracts, that are NOT daily to make the game more interesting. Then you should add some more attachments, that you can buy and that are not W-tasks. What about adding flashbangs and smokegrenades. And more different killstreaks. Also the achievement: get 1000 prokills is almost impossible and I doubt even the best players have more than 5 stormkills, so it would take a very long time to do this achievement. + if you like it
