here is my suggestion:
1. add some vehicle to the game
2 .we should be able to use the iron sight on our gun in normal mode so we can pick off snipers
3.even more weapon,i want to see the scar h,and the hk416 in the game
4.you are able to customize your character in the game like skin and all of that stuff
5.add a new map just for training
6.clan wars and you are able to create a clan
7.better graphic
