It's time I faced the cold hard truth.
I can't remember the last time I used my Holy spec.
I am a Disc priest.
In BC I was Holy/IDS (hybrid Holy-Disc build) for a really long time until I was converted by the cult of CoH and became a devoted Holy priest. But Lich King (and Moz) have slowly chipped away at my love of the Holy tree until, when I do switch to a Holy spec, I can't remember how to play it. I don't even know what the buttons do. And where's Penance? FOR THE LOVE OF DOG, HOW AM I SUPPOSED TO HEAL WITHOUT PENANCE??
Wonder what Cataclysm will bring? I think Holy's mastery thingie is interesting and it'll be a great spec, but I doubt I'll change. The emergence of Disc as the mitigation healer is just too exciting for me to go back, I think. (I mean, you know, WoW exciting, not I got tickets to Bon Jovi exciting.) I love being proactive. I love throwing shield on everyone and then ignoring them while I smite down the enemy. (Smite/Disc build FTW.)
