In destiny 1 when u made your character or maybe in destiny 2 and you thought your person was freaking awesome, you played the whole story missions and everything till u actually look at ur character and u hated the way he looked and you don't want to delete him/her and start over, so my idea is to add a place in the eververse where for some currency you can change your whole appearance .

I agree with this definitely the ability to change appearance is a much needed feature also needed is the ability to customize height and shape as in how thin or muscular a charachter is
