When I shapeshift out of bear or cat, the mana bar doesn't update immediately to display my current mana total - in fact, it displays the total amount of rage or energy I had for four or five seconds after I shift out, but with a blue background/bar instead unless I cast a spell. There anything I can do about this?
The response I got from asking this question a few times was "no" because when agUF updates the health/mana bars is when the UNIT_MANA event is triggered. If you're already at full mana when you come out of shapeshift form then the event doesn't trigger (because your mana isn't changing) so you need to cast a spell for it to show your mana. I'm sure someone could come up with a hack specifically for shapeshifting classes to force an update, but that someone is not me.
