I started in Wrath, so I don't have the long hindsight of most of you. But with every patch since Wrath came out, I would go to Elitist Jerks, find out what the number- crunchers decided the new optimal spec was, and re-spec. Weeee. The thing I like about this expansion is that my build is MY build (for the most part).

Now the min-maxers will be analyzing each encounter to figure out the most useful talents for each -- which to me, is MUCH more interesting than just telling us the optimal spec for each patch.
