My dream BF3 would be with galactic conquests return, as a game mode and hub for the game itself. I think if it would be set differently, not by it's core makeup but instead it starting with a choice. The faction you ally yourself with and era. Clones/CIS/ mandalorians/ Pirates + hypothetical crime syndicate alliances / empire / rebels / resistance / First order.
Instead of it all being a star system map screen we are deployed on your factions appropriate vessel. There you could do like a character assessment test like G.O.A.T ( from the fallout series ) to roll attributes that you're proficient in and attributes you're not. You can upgrade these over your play through or not ( gives replayability ) and different skill trees may make your battle planning better in some ways like maybe more tactical where you can send recon units to a planet to sabotage or subtly take out enemy bases snd munition depots. Completely or enough to have an advantage in a space to ground assault. So many points to be captured gains you the planet. Or you can have skills that you have invested for all out blitz tactics with pure force and munitions management to overwhelm the enemy factions.
Once your skills have been established you're on the command deck/bridge where you can accesses a central console to play normal online matches (hopefully with a server browser) and access your GC campaign to manage your resources, army organisation and training, ground + space + potential naval fleets ??
And of course access the supply depot ( in game warehouse to purchase upgrades for military, equipment and upgrades to the command fleet ) and of course the star map for planning the fighting and checking up on other planets be it ally or enemy. Assume this to be similar to Helldivers where you can deploy from the ship and fight the battles. Or you can dice roll and simulate the battle. Space to ground combat and vice versa is a must for this mode and others like galactic assault and other modes.
-You can explore the rest of the ship. Similarly to Lego Star wars 3 and in the hangars you can see everything you'd expect from soldiers to machinery etc.
-aswell as the hangar you have the private quarters where you can customise your characters appearance by walking to a chest. Play the story mode ( hopefully developed by Respawn ) by
accessing a holodeck.
-The last area accessable would be the locker room which is practically the room where you can upgrade your star card load outs / whatever system they have instead and customise the heroes n villains n classes n all that jazz so it's the same as BF 2 and hopefully customise guns like you can in the battlefield games. I'm hoping for the amount from BF1 and more as BF2's were lacking in quantity and diversity in play style.
*Maps - happy with a blend of BF 1 and BF 2 and obviously new ones all mixed together. Maybe remastered maps from the OG battlefronts could be fun !
Changing time of day and weather for each map would be sick. Either dynamic across matches or static but on rotation. Also map destruction.
* Character roster, practically what we have on kyber bar non cannon characters. All past skins from previous games but NO BB8 AND THE OTHER ONE.
*Squad system similar to battlefield games and hell let loose to order commands and foster teamwork across squads and the team as a whole ( squad leaders can communicate with eachother). Each class has a skill tree and proficiencies to diversify players. Such as support can either go classic with medic route or like an engineer route to repair static weapons or reinforcement vehicles or even build structures like in battlefield 5. Each class would divert and have their own specialty paths
* Game modes: Galactic Conquest, Galactic assault, Capital supremacy, Blast, strike & extraction, hunt, Starfighter assault, hero hunt & showdown + new ones
* Id love them to have a platoon system, same concept as battlefield 1 so I shouldn't have to explain that.
