It will be a little intricate for player that are not used to Macros, but finally I can reset and set istantly Traits to PvP action when switching job.

This news up to me was a little hidden expecially thinking about how much people asked for having the Action points liked to the job and not to the character.
This atleast help a lot for it x)
