1. Lack of an open world. This game feels like one large maze and doesn't allow for a truly planet wide exploration.
2. Cookie cutter professions (I really hate this!). Allow Jedi (for example) to chose what type of Lightsaber they want to wield (I.E. A Guardian may want to use a double bladed saber). Also Let me chose what powers I want my Jedi to use (I.E. don't classify powers by sage vs sentinel vs guardian, etc).
3. Lack of space content! I'd like a real space aspect of the game and not the mini fighter game that is complete junk. Have real maps with real ship progression and eventually multi player ships, where players could actually design and customize their interiors with furniture. (Star Wars Galaxy reference)
