First, a quick sanity check:
Before 12.0.1, Resto Shaman Water Shield will also automatically buffs Earth shield and Earthliving weapon. Right? Right? But now it is not working.
Even more interesting, Lightning shield of Enhance and Elemental still works, as they auto buff Earth Shield / Flametongue / Winfury weapon.
Anyway, i couldn’t find a list of 12.0.1 known issues post. that’s one of the reason making this post.
