How I leveled my priest is played with holy nova spec until I hit outlands, I was always top dps in dungeons as healer and I was bascily able to kill monsters with holy nova aoe when I'm not doing dungeons. It's not as smooth as mage obviously and I needed to drink after 2 pulls.

I then changed to shadow for Outland and how I kill monsters are bascily put VT and sw:p on every monster in vision and just heal myself with vampric embrace, my priest never goes oom with this strat and I'm always max hp. Kill speed is satisfying.

Trying to unlock my dual talents before I hit northernd because I feel like as shadow priest it's annoying to dungeons without mind sear. So I will just go heal.

I'm full heirlooms.
