Aspect of the Tempest Tornado passive not triggering

Hello a bug i found that is in the game for more than 2 years.
Please don’t mind any misspelling or error, english is not my native language.

The Shaman Skill “Tornado”, as a passive skill “Aspect of the Tempest” that is not triggering or don’t show any form activation (logo, aura, etc). And any subsequent passive of “Aspect of the Tempest” in not triggering too. As i had tested, using “Tornado” actively, or passively by triggering it with any other skill or passive, and it don’t trigger “Aspect of the Tempest” in any way.

Aspect of the Tempest in the skill tree

I can’t provide any form of proof, as nothing triggers or appear so it will be useless. I also respec my whole character so i can’t provide any logs anymore.

Thanks for anyone for any replies, that could help me understand or testify about this bug too.
