Update: The game is boring now because of "the meta". There's only one way to play the game that clearly outshines all others. Medic + SMG. When you run this combination, you run faster, recoil is negligible, and you can heal yourself infinitely. That's the only way to spend more time alive than you are dead in this game.
You thought you could hunker down with an LMG and empty your 100-round drum-mag at those runners-and-gunners? Nope! First off, if you have an LMG, you'll be moving slower than they are, so by the time you get set up in a spot, the frontline will have moved and your position won't be good anymore. Secondly, they'll just click on your head and kill you because they have no recoil, while you have to deal with slow movement, ADS, worse accuracy, and higher recoil. Also the bipod in the game is broken.
Wanna just fire in their direction and keep them suppressed? Suppression does not exist in this game! They'll just calmly line up a shot while bullets land inches away from them, due to the poor accuracy of LMGs
I'm continuing to provide suggestions and feedback, and hopefully the game will turn itself around and make all the classes and playstyles viable.
