I tried Shadow priests before and I read 'you should always try to stay in shadowform unless you're healing between fights' - so I tried to stick to this and my survivability plummeted compared to disc.

I want to try it again, only this time - I want to use holy nova, I want to use heals - I'll go into shadow once I feel save to do so.

Has anyone had experience with this?

If I master this I feel i'll have more tools at my disposal - higher killing power and mana regeneration - just need to not die
