Some thought to improve the game :

-More map.
-The war between the 3 factions in the menu should be balanced from 'the faction with more people win' to 'the faction with the most active people win' (with a ratio).
-Please there is the same problem with R6, put a button 'return to menu' during loading screen and matchmaking search cause everytime i encounter a bug i'm forced to close the game.
-Fix server lag.
-Balanced the game ( Like adding a time limit on the shield for the tank class ).
-For one vs one and 2v2 add more place in the same map for fight.
-Key customisation for gamepad?

That's all.
