One thing I hated with the changes done was transfering 3/4 of the health cost into a magicka cost on either morph making a ressource free support burst heal be taken away from healer and tanks while taking the some of the identity away with bloodmagick becoming magick with a bit of blood instead
One thing that made it even worse for me is the self targeting aspect, while great when you need a strong burst heal, it also make it impossible to cast it twice to heal others
Even when an ally has 50% hp in front of me the skill targets me for my missing 140hp instead in most scenarios, and with the massive magicka cost if not a mag archetype build you only have 3-4 casts before being out of magicka making those occurence even more punishing as it waste a sizeable chunk of your magicka reserve
