I've heard rumblings that Druids attempting to off-spec heal in low level instances are having a bear (*rimshot*) of a time with it despite having Int gear. Understandable since Nourish comes at 78. I have quite a bit of experience healing as a Druid at 80, but this is my first priest.
I haven't done any instances with her yet because, honestly, I'm just leveling too fast as it is, but I finally saw the light (Vuhdo), and I'm itching to try it out, but I'm apprehensive that all the kinks haven't been worked out yet, with spell scaling, mana regen changes, talent tree 'boons', etc.
Anyone have any experience post-4.0.3?
