Gamebreaking primordial wave bug

As an ele shaman, if i cast primordial wave and a priest randomly greater fades it, a DH imprisons target, or various other forms of immunites are present on target, that will prevent my character from getting the primordial wave BUFF to cleave lava bursts. Please fix this as its a MAJOR hinderance and damage loss for someone to UNINTENTIALLY “counter” this ability.

Those abilities counter it, whether the player meant to hit them or not.

Yeah it’s kind of annoying but I feel like the intent here is that if you fail to connect with the ability you don’t get the buff.

It’s annoying though when your DH teammates randomly imprison your target but that’s the pug life.
