Hello, I am new to the disc class. I was shadow for the entire LK expansion. I am trying to be disc. for Cataclysm and well I'm having mana trouble. After every fight I have to get mana. I don't know what's wrong. A tank said that they nerfed priests, but I don't know. I use grid and my rotation is just shield, renew, flash heal. And so on. I've only done 3 dungeons, I only made us wipe once because I didn't have any mana. I don't know what's wrong. My gear is 319... I know you need spirit > int and stuff. Can anyone help me?
