I leveled priest a while back, went Shadow and took her to level 50. The server was always full so I popped to another and became addicted to Retadin(75 now) and have a new Lock(23) so have not returned. I actually am going to remake a Priest on the new server because I want an Ally not a Horde priest(<3 Draenei).
But in this process, I noticed Holy Fire did a TON of damage. I was curious if anyone has "parsed"(do they have those in WoW?) the damage between going full Shadowform and using Shadow only vs using Shadow mixed with Holy Fires when CD was down. It's just hard to see the +15%(?) beating out the constant Holy Fires and ability to self cure.
Granted, I was level 50, so if there are new/major Shadow spells to aid in this, I'd love to know :) It just seems Holy Fire spanks Mind Blast in both damage AND mana cost, so I was curious how it all adds out :)
