From what I've been understanding, Blizzard is going to implement a Dual-Spec, which is simply as it means, Be one spec, then press a button, and BAM your other spec of choice.
Example
Retribution Spec and I'm needed to tank, well I press the button to change to my other preset spec which would be Protection, and I wouldn't have to pay the 50g fee :P
Have you guys heard of anything like this? I hear about it ALL the time, but haven't really found anything regarding it.
