I haven't played Shadow, or cast offensive spells other than Smite really, in a long time, since Devouring Plague was my Undead racial and it had, IIRC, a 2 minute cooldown. My new priest is only level 22, so possibly this changes later, but I'm looking at the new DP and I'm wondering:
Why would I ever use SW:P instead? Unless it was when fighting multiple mobs to DOT everyone up?
I'm not talking about boss fights where you obviously just use both, but shorter fights where more than one DOT is a waste of mana.
Is there a point where SW:P gets superior, or do you just use it a whole lot less now? Am I missing something?
