Battlefield 1 DLC: 10 Specific Things Fans Demand
2. More Weapons And Vehicles
Going back to the whole 'sparsity of content' thing, Battlefield doesn't really have all that many weapons to get to grips with. Currently, the assault class has about six: three submachine guns, and three shotguns; not exactly that many for the ostensible granddaddy of the FPS genre, let's face it.
This makes the matter of addressing the lack of weaponry all the more pressing, because once players master them in all their variants (of which there aren't that many to begin with), things are going to get a little boring. The addition of new units should necessitate some more weaponry however, so rest assured that more are on their way.
I know more bolt-action rifles wouldn't go amiss, as would some more automatic weapons (if there are indeed anymore to find). Regardless, the lack of an extensive armoury is something DLC will have to take a look at, especially if DICE wish to preserve the meta of the title's multiplayer.
