I dont know if this has been mentioned before, but if it has be prepared for a repost.
Anyways, with the current release of the legacy system and new races becoming available, I think it would be a good idea to add a way to edit your characters looks.
Wether it be for a "salon" that costs credits or be a with real world money, I think it would be a good idea to let everyone be able to change how their character looks, be it one time, a few times, or as many times as they want.
For example, if they unlocked a new race through legacy, they go to the "salon" pay a few credits, and edit their character however they like.
This way, people who have made their characters before legacy do not get screwed over and can roll in style however they originaly intended or if they want to add a fresh new look to the character the've worked ever so hard on they can.
