I didn't see anything diminished in the efficiency of my healing spells.
As for my aura it hits for about 20 more than before. ( from 20-26 with crits in the 40 Range to 30+ with crits in the 56-65 range ).
Those that see nerf in healing needs to take time to think. And look at the items they use. Potency Items won't do it anymore. They need to pick up Devotion Items.
This is the so called nerf :
before U-14 Potency Items worked on Healing spells, making Devotion items redundant, as Devotion was limited to Healing.
after U-14 Potency Items works at half power at best on Healing spells, while Devotion works at full power.
Buffed, with the right items.
The rest is mana management and metagaming.
