Dual spec please

Design decisions that changed during TBC. The decision to add dual spec was made during TBC based on what was happening in TBC. That it didn’t get implemented till wrath doesn’t mean it wasn’t decided on during TBC.

You can make the argument that coming out of vanilla dual spec didn’t seem necessary. But with all the changes in TBC that decision clearly changed. You have arena’s and pvp becoming more prominent, hybrid specs besides healing became much more viable, in general there were a lot of things in TBC that cried for dual spec that weren’t the case in vanilla but became painfully obvious in TBC.
