Lets talk about balance real quick, I had the game on hard because im not new to FPS games and one lower difficulties im sure the problem im about to descripe is lessened.
I have an anti-vehicle rifle that your can only use if prone. I can one-shot an admored car but the big bad flame thrower human, takes two to the head to kill. This is when I realised they didnt make it harder, they just turned everything into a bullet sponge. Lazy.
2nd offense, I had a scoped infantry rifle and i was out ranged and out accuracied by the AI MG nest. No way a WW1 machine gun lazes down at a range a sniper is essentially ineffective.
Balnce issues.
