Nobody will care, but meh, I got time to kill. I'm currently leveling my Priest with my sweetheart, a Prot Warrior. I was leveling Shadow. It was a pain. Before the massive nerf to mana regen, I was doing more than fine stacking spirit like mad. After the nerf, ouch. I was drinking every other monster. :S
Lucky for me, I was already 55 and the wife around 53 so it was not long before we moved to the Outlands. I decided to try another spec because she wanted to do large mobs and as Shadow, I couldn't effectively heal and I was drinking after each pull. I had the choice between Holy and Disc and since I started the Priest to be Disc at 70 (long time in the making), I specced Disc.
And man, is it fun or what?! PW:S is sssooo powerful, I can just shield her twice in the fight and have no heals to do. And Penance? It's cool looking, the healing is really powerful and the damage/mana is pretty good. I'm having a blast.
Aaaaand that was my story. Sorry, no QQ, just good things to say!
