Deathlace

In raids that were available on Nostalrius, I only went OOM on Nefarian unless I tryharded with Demonic Runes. No doubt as harder raids open up, the number of these fights will go up.

I did pure Arcane raiding on Nostalrius and cleared all content. It's worse than Frost, but the difference isn't as major as some people are claiming in this thread. You'll have to tryhard with pots/runes because it's extremely mana inefficient and you'll gear differently to Frost. I don't really want to get into arguments on forums, but please feel free to PM me if you have any specific questions.

I actually plan on doing a Smite Priest this time around. Should be fun!
