Is there any addon that shows a castbar for heavy attacks so you can see when it is OK to release to still get the mana/stamina back and benefit from any heavy attack bonuses?

Solution is called Heavy Attack cancelling . You do it like this . Hold down your Heavy Attack . Never drop it . While your character is charging the Heavy Attack , use a skill but still hold down the heavy attack . The skill won't go off immediately . It will go off immediately once the Heavy attack is fully charged . That way , you don't lose time on your Heavy Attack and use the selected skill without losing time and the quickest possible way . Remember , don't let go of your Heavy attack button .
