Is there a way to follow a name change of a guildless player?
Not location. Just simply knowing what their old name is if youbknow their new name
Yeah, unfortunately not. Hopefully they can one day have a feature that allows you to track their past names, as sort of an alias thing... but some people change their names due to reasons like if they're a trap and need to go unnoticed, or under a lot of heat and need to escape a situation or people hunting them down.
