Some things I hope they add eventually, maybe in an expansion.
Space pvp:
WZ-battlefront as a primary example, fight to kill a Imperial or Republic capital ship
open space- customizable (colors, other appearances) ships and allow guild to bring and control their own guild ships (like in Revenge of the Sith- the rescue mission for palpitine). also a way to finally use escape pods.
Race Tracks:
swoop tracks or some non-combat open world track (either that, or free-for-all tracks). also, customizable speeders/swoops
Pazaak/sabacc:
a good card game
Arena:
who wouldn't want to fight in the geonosian arena? make the rewards about 3/4ish as good a wz so that the people who arena fight are doing it for rankings, not because they have to to get gear.
Improved Cantinas:
place for pazaak/sabacc. also able to watch arena fights, huttball matches, swoop races. ability to place bets on arena fights, huttball matches, and swoop races(credits or valuable items). in other words, a place to be while in a city.
