Some things that i would like to see in the game,
1. Robes for the Jedi that are different colors, not just the usual brown.
2. Robes that don't have hoods on them all the time.
3. Quick travel to your ship
4. Stronger Guardian moves
5. Customizable ships/Names
6. A way to change your Legacy name
7. More color crystals, like some more colors.
8. I also think that if you have a double bladed lightsaber that you should be able to put 2 crystals in it.
That is just a few things for starters.
