This is a known issue, apologies for the negative experience! We have a planned fix for this, but unfortunately it requires a larger technical change for the skill to be fixed properly, so it likely won’t be ready for a 0.7.7 hotfix.
To address your point about nerfing vs bug fixing-- in 0.7.7 we made some technical (not balance) changes that inadvertently made Aura of Decay far stronger than intended, completely trivializing content on some builds. By fixing the bug, we returned the skill to the power level it had in 0.7.6. We’ve heard the community feedback that Aura of Decay doesn’t feel strong enough for the investment you have to put in, so I’m sure we’ll revisit it in the future.
