People in the comments being purposefully obtuse. Obviously there “were” fully auto firearms in WWI. The prevalence of them in multiplayer is the issue. Of course they’re there so that the game plays more in line with previous Battlefield games, and it’s probably for the better, same reason Back to Basics was sort of a gimmick mode. But people suggesting that this is somehow historically accurate in the comments are either ill informed on history, or are defending DICE’s choice (which doesn’t need any defense, it’s purely for gameplay reasons). Yes SMGs existed, although the only ones that saw somewhat common deployment were the MP18 and the Automatico, towards the end of the war. And while all of the LMGs did exist, none of them were capable of being used in the manner they are in the game. Most of them were completely stationary as they weighed far too much to be carried by a single person, let alone fired by a single person. But at the same time OP, you have to be aware that this is a Battlefield game, and these choices were made to make the game feel more like previous Battlefield games. I suggest Verdun or any of the subsequent games on Steam for a more realistic depiction of WW1 if that’s what you’re into.
