It's entirely possible that's the case and i'm wrong. I'm not trying to say this is how it will be for sure this is just my thoughts based on pretty deep understanding and experience of the class and game along with strong gut feelings.
With auto attacks being as strong as they are now along with reduced cooldowns/GCD, and faster rage generation i just can't help but feel like haste will be MVP. Maybe crit will just be better though, we'll see.
