Bump. This needs a fix. I already have so many macros wasting space on them for something the game used to handle fine natively is annoying. It’s very annoying to swap specs then start a arena only to realize the button you are mashing is not on your bar and have to open your spell book mid PvP to re-add it for the 100th time.
This happens for sure with Light’s Hammer (holy paladin), Seraphim (all paladin specs), and Holy Avenger (all paladin specs)
