So, I got a group earlier which made me question how Scaling actually works with Healing, as there seems to be no rhyme or reason within it.
I was, at the time, roughly Lv45-48 or so and I was a bit undergeared I will admit, a Holy Priest.
In my group were two DPS: One level 80 with 4385K health, and a 72 with 672K health.
It was a Dire Maul, and I noticed that when I casted Flash Heal on the Level 80, I would heal roughly 25-30% of his life, sometimes getting a crit for upwards of over half his life. He goes down to 70% or so, one Flash Heal zips him to full. He was a melee of some sort, I don’t recall what, though.
The 72? They were a shaman, not sure what kind, I don’t remember. I think they might have been Enhance.
She got down to like 50%, and I threw a Flash Heal on her, and for a moment, I thought I was silenced or stunned or something and the spell didn’t go off, so I casted another Flash Heal. She gained about 10% of her health. I casted 2, 3, 4 more and finally she was almost full.
This makes zero sense whatsoever. I didn’t see any debuffs on her that would reduce her incoming healing, and I don’t remember seeing anything on the melee that should increase healing received and the next dungeon, I got into with that same shaman, and again, my heals are barely touching her while I can zip anybody else to full in a couple Flash Heals.
