How about Steampunk setting for next Battlefield or can you fix BFV with this patch? I mean real steampunk with steam weapons, technology, maybe robots, special airplanes and maybe even magic? For example games like Frostpunk or BioShock Infinite, anime Lastexile or Castle in the Sky. Anyway your game far from reality, so why not?
Plus CoD already took fantasy setting of the future, so better take fantasy setting of the past. I think it will fix your problems with hater's comments about non-realistic games, because it will BE non-realistic.
