More than just 4 maps, bigger maps, better story missions (instead of every mission being deploy dinklebot and defend, rinse and repeat), no more "new" missions that are just old ones in reverse, an actual use for our space ships, bigger vault, vault on space ship (cause why would you store your weapons on earth when you're goin to Mars?), randomized enemies on patrols, much much bigger public events (more like defiance), better armor perks like % to ranged defense or melee defense or how about like the enemies have? Increased resistance to arc, solar or void. I'm sure I could list a ton more lol.
