I could be wrong but it seems to me (if you believe the simcraft etc) that it isn't broken specs that are hindering hunter dmg at the moment but rather the class itself.
The reason i think this is that the simulations put all hunter specs within a 5% top dmg deviation. However all of these are fairly low when compared to other classes.
So i don't believe MM for example is broken like alot of people believe I think Hunter's are slightly in need of a small push that boosts the class as a whole.
And their are still too many bloody buttons!
