Ahh, I want this so badly! I've been wanting to use my Fantasia to turn my Miqo'te main into an Elezen, but I've been holding off in wait for some name changing service to be implemented. I'm a roleplayer, so I'd like my name to be lore-abiding and I don't want people looking at me funny because I'm an Elezen with a tribe name.

If it was a paid service offered in the Mogstation, I would gladly shell out money for it.

If it's any comfort, perhaps there could be a trail, or an annotation when you hover over the name in your friend/block list that says something along the lines of, "Previously known as ____."

As long as the blocked list doesn't remove people when they've changed their name, I don't see an issue? And so what if the players with stupid, gross names want to change them to something nicer? If they change them, then there will be less stupid, gross names running around, thus less of a problem.
