Back in the days, I had an addon that tracked rep for each zone.
It basically switched the "Show as Experience Bar" each time you switched zone, to that rep you had chosen for each zone, and if you han't chosen for a zone, it showed a default rep, you also had chosen....
Sadly, there was no development on it, since WotLK or Cata, and have now stopped working completely..................
Does anyone know of a similar addon?
