I think an appearance change feature would be great for ESO Plus. For those of us who are a tad obsessive compulsive and are somewhat vain, an appearance change feature would be a strong selling point. It could just be the character customization section from the beginning. Some people want a "barbershop" or some place we go in game to do this, but that only delays implementation of the feature because the developers have to create that. The character creation section already exists. So simply allowing us to return to that would be much easier and allow the feature to be implemented sooner rather than later. Yes, everybody wants everything now, now, now, but seriously not having to create a physical barber shop in game and simply allowing us to return to the character customization section ad nauseum would be awesome! I have a feeling this would get a lot of folks to hop on ESO Plus train!
Something to consider.
