Yes, this is why:
No seriously, I thought it would be interesting for each own to say what they enjoy about Priest?
What do you like about Priest?
I'll start by saying the Shadow aspect of Priest is very appealing in term of gameplay and just pure look of awesome purple magic.
I like how I can play Shadow Priest without having to look down on my buttons as often as other classes, and I feel more free and less punished for just using spells I want, and by switching talents you can change the entire way you play, that is pretty cool I think.
Wish I could say more about Holy or Discipline but it's one of the specs I have not played much yet.
