This is copied from the 1.19a patch notes, and is regarding the new "action bar saving" feature introduced in 1.19a.Any recast timers in place will not be reset by changing classes.
Perhaps I am misinterpreting what is said, but when I change a class, every single ability on the action bar has its cooldown reset.
The occasion that I find this most distressing is if I need to change to a crafting class temporarily to repair someone's gear, craft a replacement item, or something similar -- in this case my (Rebirth) ability's cooldown is reset to 30 minutes when I set back to CNJ.
Is this feature working as intended?
