yeah, same happened to sub rogues
it took them literally till 7.2 to listen to advice.
granted the new version is probably the best version of the spec like, ever maybe. (excepting some fringe cases where the combination of setbonuses, etc made it super amazing like HFC, and dragon soul) but it did take them like 1,5 years.
I'm just saying that whenever someone complains of a spec's state in alpha/beta people immediately tell him to "it's only alpha relax" and then it gets implemented. like the reason we whine is cos we dont want that version of the spec :P
