Vehicle options as a travel power
Updated profession system that adds to the crafting/mission component. (think of it as having a dual identity costume where you aren't recognized and pick up tips, missions, or scavenge for crafting materials.)
Apartments/Housing/Secret lairs aside from bases. (I can have my batcave as well as zone into the JLA Watchtower dammit!)
Nemesis and Sidekick (pet) options ala the SWTOR MMO: You can design their costumes, origins and maybe power sets... But there's a specific storyline that carries your character through the game. Your sidekick can run side missions or tasks for you. They can switch between tanking, buffing, healing,.
Major costume upgrade that gives more options to color and accessories. Literally the only thing i liked about Champions online.
MOAR POWERZ and Epic Power Pool options.
