@SolaireSundancer that's very true, see the thing is with BF1 and BF5 is they were based in history so their mechanics with bullet trajectory, velocity, and damage were all different to the modern warfare of BF4, see the same will be with battlefield 2042 now since it is in the future, my guess is, there will be higher velocity on all machine gun modes on all jets, the special weapons that you can choose will have some crazy weird ones while the still default but improved tracking lock-on systems of the rockets ['improved' because it's in the future] but the basic stuff will definitely still be there, the way they work, the keybinds, the dog fights, the game mode 'air superiority [ most likely ] like BF4, the machine guns. the special weapons, maybe a quick repair? a repair system, etc.
but the way they work with maybe Russia has better damage? As in they have better weapons on their planes. whilst America might have better agility coming to dog fights, being able to do circles until the American fighter is behind the Russian one if the Russian one didn't kill it in time. [vice versa in the damage and agility on each side]
But in general, sides will have certain abilities, and different types of planes on each side will be better at something, but it will always be (MOSTLY, hopefully) balanced since EA tests it a lot, and the basic mechanics will be the same
Have a good day! @SolaireSundancer ,
Positiveeeeee,
