I'm sure it's possible but I doubt it would be on the priority list. I can't imagine the hoops a developer would have to jump through to get that kind of approval.
DLC before dyable armor with the current ones we have is crazy work. I wonder if the DLC ones will be dyable when they hopefully eventually add the ability to the existing sets.
Hello! I was riding around Navezgane and randomly saw the quest flag for 'Restore Power' at the Rippon residence, even though I did not have a mission at this location. I was playing privately offline, and no one had ever joined this world. I was only on tier 2 missions so it is definetely a bug.
