I would like to see more characters and ships originating from Legends as well as ones currently in the game but sadly are restricted to being NPCs like the Rebel Pilot, Rebel Trooper, Imperial Officer, Calo Nord and Revan Sith Trooper.
Also, more modes of gameplay to play whilst waiting for shop items, challenges and events to reset as well as to spend the excess credits and tokens we have which currently feel meaningless. Maybe have Sabacc and Pazaak to play where you can bet the excess tokens and gear we have for better rewards or items we need.
