1. Lightsaber color crystals should not be faction specific. Actually, they should stick to SW-Canon. Blue, Green, Purple, and Red; however, it is fully understood due to the diversity of the player base and their desires to have all colors of the rainbow available.
BUT, Imperials can equip every color except Lt. Blue, and Rebels can equip every color except Purple.
2. There should be more customization and crafting mechanics for lightsaber appearance.
3. The ability to modify one's appearance
4. The ability to modify the appearance of wearables. [from head to toe: color. style, etc.]
There are MANY that feel this way... Please fix, especially #1
