So -- I've been really bored on my main lately, and I've decided to start a new toon as soon as 4.0.3a launches. I previously had a lot of choices, but it has been boiled down to this: Priest vs. warlock.
As priest, I would of course be shadow, and as warlock... well, I guess I'd be Demonology, since it sounds coolest.
Here's my question: which is the funniest spec to level? Shadow or Demonology? Which is funniest at 80? And why?
