"Can’t drink Major Healing Potion or eat Major Healthstone while in form"
I have a solution to that (You can instant power-shapeshift with the BFA-macrosystem):
#showtooltip Major Healing Potion
/cancelaura [stance:2] !Aquatic Form; [stance:3] !Cat Form; [stance:4] !Travel Form; [stance:5] !Moonkin Form [stance:1] !Dire Bear Form
/use Major Healing Potion
/cast !Dire Bear Form
You are welcome - Disadvantaged solved
