Is there a reason other than "choose wisely when creating your Guardian" that we can't edit our Guardians' appearance, even if it's something that doesn't affect the race or is generally inconsequential (like hairstyle, hair colour, or exo faceplate colour & markings)?
Is there any possibility for that functionality being added in the future? Maybe Eva Levante had enough of shaders and emblems and now she's back as the resident hairstylist (I don't know, I'm just tossing stuff out there), or it's an option on the Character Selection screen?
Truthfully, I'm just regretting my choice to give my Awoken Guardian that mohawk, and now I keep her helmet on at all times because it's a bit obnoxious for me. I just wish I could change it.
