Well at least they noticed the bug and are still trying to figure out how to make it happen. Props to them!
Curious what it was doing to warrant a complete removal till its fixed, usually they let things like being too strong or have unintended effects stay until they make the patch. Must have been fairly extreme.
Or they could fill the class fantasy of being a master in harmony of the elements by making that talent have them be permanent pets. The opposite of mage's Lonely Winter (or how Glyph of Water Elemental worked when we had prime glyphs.) I'd main my shaman again if they did that.
