the main criticism against Battlefield 1, is that it's not historically accurate and that it lacks weapons. The way DICE can address this is by:
- Adding a mode called trench warfare, for all the people who are more into the historical aspect of it. 64 vs 64, or 32 vs 32, no respawns, only bolt-action and semi-automatic rifles. Or let people rent their own servers so they could do it themselves. A perfect map for this would be Saint Quentin Scar. This would be more accurate to what WWI was like, and thus satisfying the critics.
- If the added all the countries in a DLC, or multiple dlc's that were left out, such as: France, Russia, Italy, Austria-Hungary and Bulgaria. By adding these countries, they could add the weapons that they also used, thus adding more weapons to unlock, and adding a more historically accurate WWI game.
This would take a while, and probably multiple DLC's, but it would definitely make the game a better experience for EVERYONE!
