In the first post about dual specs I asked how you'd be using that alternate set up. Enough people responded with 'tanking' or 'healing' that the next question is apparent: in light of Blizzard's announcement that dual specs will only be available at level 80, do we really think that's wise?
Spec and gear will only take you so far - and talent isn't the same thing as 'talent points.' During the leveling process is EXACTLY when we need access to dual specs. Having that ability only at the end of the journey robs us of the opportunity to arrive at 80 with skill, and not just gear.
More and more, the concept of dual specs seems to be designed as yet another way for affluent 80s to spend their gold, instead of promoting additional tanks and healers at all stages of the game. And that makes me sad.
