Arielle's already checked and it's just a wording change.
Also, that's the kind of change that you just see and ignore. Everything about it screams datamining error; they're not going to give a tank permanent 40% increased healing taken, and even if they did it wouldn't need to still cost 50 rage . It also seems dramatically out of place for a simple glyph (though rdruid efflorescence does too, I guess), and would really just be a random way of trying to make that glyph useful.
Not everything on the front page is meaningful. In fact, stuff in green text like that usually aren't.
