I agree for enhancement, probably ele too. But how would this work out for resto sham? I could see blizz adding it for enhancement and ele, def don’t see it for Resto.
Stormreaver should be baseline for enhancement/ele, not a pvp talent, because pve shamans also struggle with using their maelstrom stacks for healing instead of damage.
Resto Shaman issues revolve around getting trained by melee. Which is also a mobility thing. They have plenty of instant healing with Riptides, Natures/Ancestral swiftness, healing stream, healing tide, etc.
