I hope MW is still the most fun healspec after this. :3 It's always infuriating when they give explanations for cutting things and then expand on that feature (in similiar theme) on another class.
As for the WW changes, i actually love the new mastery even if the effect itself is bland. Flat damage values isn't all that exciting, but i like that we're encouraged to mix abilities - it's one thing i felt like never worked with WW before.
edit: regarding Tiger palm, they are replacing Jab with that by the looks of it, for WW.
