Gravity
I believe that there should be more of a realism to the game. If your character or a nonplayer character and gets to close to a cliff he, or she should fall off. Things like gravity I think are important...
Perspectives
I would like to see a first person and a third person view in one game.
Characters Physical prowess, and realism
I think that there should be a lot more moves that your characters can earn to make the fighting experience more realistic... Also the ability for all Jedi characters to have a force jump,and non Jedi to have a regular jump option.
Vehicles, and transport animals.
Greater control of the Ebon Hawk would have been great. Also control of Lanspeeders Sandcrawlers and animals like Dewbacks, and tauntauns.
I would also like to see more quests so that you can increase the degree of level ups with more experience...
Glitches
Oh and Please get rid of the glitches....
