I'm really new to this whole priest thing, I was wondering now that I've hit 10th level if I should go shadow until 15? I'd like to start healing dungeons at that point and can respec or would I be ok just taking disc until then and not worrying with the respec?
I'm going to be doing a LOT of dungeon leveling once I hit 15, so I know that I'll need disc then. At 30 obviously I'll get dual and spec shadow for questing in between queues.
Disc is better dps class than shadow until Northend and lvl70 or so. Spammable hard hitting nukes with automatic self heal component(disc) vs shadows weak slow dots and mana troubles.
