You know, I would actually like this if done correctly. I'd like the modifier for MAB to be so significant that in gearing for melee you were actually better off in DPS choosing MAB over haste on gear, to completely take haste out of the equation for RDM. Of course we'd still use the spell, but it would be interesting to see RDM dismiss haste on gear in favor of MAB when meleeing. And I'll admit, it's mostly because I hate the look of our available haste gear and kinda like the new AF. Well, except the hat with the mullet and spit curls.
I say "correctly" because of the potential of MAB modifiers to go the way of the on-hit enhancing skill bonus to enspell II. As has been said, the modifier would have to be pretty large.
