The only thing I don't like about the default UI are the conflicting styles between the UI and the chat bubbles. They should have either made the chat bubbles same futuristic style, or the whole UI the old-ish chat bubble style...

I dont mind the UI being a bit futuristic, who knows, it might fit into the new world. Since we're getting magitek mounts and all, it seems they are going into that direction, so a bit of a tech-UI is fine.
