I think a major boost to the game would be a random April Fools event playing every weekend.
WW1 and Interwar, so there are more available.
I don’t think they could keep that ball rolling, but adding an optional removed mode (like Air RB EC or that moving frontline ground RB mode they tested a while back) that changes every weekend would be quite nice.
Agree with most, idk about 3, and 4 is slightly questionable. A big one for me is a Multicrew Combat system, be having a co-pilot, or a tank commander and crew, would be a great addition. Having a weapons officer in, say an F-14 or F-4, would be amazing, you can deal with flying, and they can deal with weapons, overall would add to the depth of the game. Also see a “all out war” mode with maps the same size as Air Sim EC games, and have two “teams” and multiple companies on each team, and give some more vehicles some Amphibious capabilities, as well as more vehicles types for the modes. And a major one; add infantry to IFV’s to give them a full crew, and maybe only IFV’s can capture strategic points?
