I have no idea how to adress this, because I don't know the term for it. Therefore, I've googled myself silly and found nothing valid.
My problem:
Prior to patch 6.0, when I would cast a heal, I would see a transparent piece of the targets healthbar being added to show how much was being healed. Very useful when healing in a hectic dungeon or raid.
After patch 6.0, this is gone.
Is there any way to turn it on? How am I suppose to pre-heal now? Just learn the exact numbers my spells heal and calculate whats best for each situation?
