IT happened. I went OOM (twice!) while raid healing as Holy. The Imp was still resting. I had no more verses left in my Hymn. I even downed a bottle of Raider-ade (Mad Alchemist pots aren't delicious, but I do like those electrolytes). My Frost Wyrm flask unhappily sat in my bag while my Mojo flask screamed for help. Replenishment came to the rescue, but didn't bring enough friends. I could have called out for an Innervate, but the tree was having mana issues of her own, and frankly I didn't remember that option- it has been so long that I needed one.
I look at my gems and wistfully realize that I need less fist and more legs. Goodbye Runed, it was nice getting those monster shields in Disc, but Holy needs a hand.
I am just now getting into ToC with my guild runs. I think as we become more familiar with it, the raid damage will lessen and I can adjust back, but until then, Holy needs more mana.
Any other Holy/Disc priests that have this issue? I'm still working on some upgrades, but I don't feel undergeared as Disc at all, and have had no problems (until now) as Holy.
I logged out in some items not normally worn (head, trinket and OH). Normal unbuffed stats as Holy are:
Int: 1248 (22303 mana)
Spt: 856 (regen 584/332 79 from MP5)
SP: 2295 (crit=21.9% haste= 10.16%)
