Just posting for context since its come up a few times.
The issue being is that this change absolutely destroyed a large chunk of the power this talent provided, and this talent is our primary aoe cooldown. There was no buff to reallocate power. There was no mention of shaman damage needing to be changed, but it was. The issue in question persists in other classes since ele shaman apm wasn’t uniquely high. The talent in question has worked this way for at least three years, and was even worse in regards to their justification during the end of bfa. This change happened without even a weeks notice after the raid came out and people were already mostly decided on mains. A response would be fantastic, but a reversion or compensation buff would actually fix the issue since blizzard took it upon themselves to nuke a mid tier dps from orbit, in m+ especially, to fix a so called accessibility issue.
