I would honestly prefer a vanity piece/customization option for our armor instead of more character face customization. You rarely see your character out of his armor, so it'd be nice if you could get something really unique to wear. Not the class items, those are cool but I want something not everybody has. Maybe you could choose to have put bullet holes in your armor, or like a big ass slash where you tangled with a hive knight. After beating certain bosses or tough enemies you could unlock new things. Like idk a smoldering hole where you took a round from a hallowed acolyte. Stings a bit, but you turned him to dust. I think things like that would be awesome. It'd give each guardian a visual reminder of their own story and give other guardians the ability to see what their brothers and sisters have accomplished. Because having the gear doesn't tell anybody anything other than oh you got lucky and got an engram drop. But if you had unique armor battle damage/accessories that were based off of what game content you had completed that'd be awesome. Like if you best the servitor in the earth strike, you can wear a piece of the destroyed machine as a trophy dangling from your armor. Or just something to let people know "hey I've killed this guy". It's a weird comparison but I'd like each players armor to be like a charm bracelet, each little dent, bullet hole, slash and accessory tells a different story, that you know simply by looking at it.
