Hello, I'm unsure if this question has been asked before, if it has I apologise.

Currently i have Two characters, one is level 60 and the other is 20 and i wish to swap their names around. as far as the current system goes it states that
  • You cannot choose your character’s current name when using this service.
  • We cannot guarantee that your preferred name will be available for selection.
  • You cannot choose a name that is currently in use by another character on the same World.

So my question being, Can I swap the name of character (for simplicity sake) A to character B.

If it's not possible, the only solution i can think of is
Change character A's name to C
Change character B's name to A
Then change C to B's name

ALSO, what is the cooldown period for the name change?
