Now first off I want to clarify that I don't play a priest, but I'm asking this question on behalf of someone that plays one. Not knowing the class extremely well I thought this might be a decent place to get an answer from people more knowledgeable about priests than myself.
Anyway, the guy wanted to know whether the spell Atonement proc'd the trinket Eye of Blazing Power. Apparently he did a BH and it only proc'd 4 times during it, and he was wondering whether he should use that trinket versus using a Rune of Zeth.
