More customization in general is the way to go! I know most people are just in it for the guns and fighting but I know a decent amount of people like putting time into their characters appearence even if its just for the odd cut scene or around the tower. In saying that though wouldnt making your character taller and thinner give you advantages in the crucible? I dont mind not being able to change height and body shape but I definitly want more facial, hair (and maybe voice) options!
