Dynamic Day/Night Servers Based on Actual Time
Maybe it's too late for BF1 but perhaps down the line for other Battlefield games, I think it would be a good idea for some servers to have a dynamic day/night cycle that changes based on the server's location. So, if it's a "US East" server and it's dusk there, then the sun should set on any map played there; if it's night time, then that map gets played at night. This effectively means that Night Operations automatically come with all maps. You could still have static time servers if some maps are best played at night. But at least in BF1, night maps such as Prise de Tahure are very much enjoyable with the sun up IMHO.
Just my 2 cents.
Some servers could be set to +12 hours. So, you get half the servers on local server time, and the other half of the servers would be as if they were on the other side of the world.
