IMO yes, because in much of savage, that will pretty much equate to giving us a 650 potency 20yalm aoe heal + regen every minute without any of the limitations or quirks of Earthly Star.
Likely because you haven't done the content where it's actually rather powerful? In this week's O3S for example, I cast 45 aoe GCD heals over 11 minutes, that's an average of a confession every 14.6 seconds. Where's the skill ceiling in that? I'd just be sat at 3 confessions long before the ability was up again.
Even with these sort of changes, I still don't think it'd be terribly useful outside of Savage TBH, it's much like Cure III in that it's just overkill in the vast majority of casual content out there.
Giving the class that's already the strongest aoe healer another significant advantage over SCH/AST isn't that great an idea given how incredibly healing centric the latter half of this savage tier is. I'm sorry that you can't see that =(
