Battlefield only needs 4 things. #1 Terrain deformation. #2 Total destruction. #3 AOE point gain modifiers for team play. #4 BeamNG style vehicle physics.
That is it. No special classes. No stupid game modes. No excessive future tech. No oversized maps. No AI assisted game development. No story. No campaign. No excessive nonsense gun attachments or skins. War. The game is war. Stop trying to make it NOT war.
