This is what I suggested in my thread not too long ago. I was summarizing what I said earlier.
In my perspective this would easily give both good usages.
Take fights in the raid, gnarlroot, Larodar, council, fyrakk would all see good usage of halo. Adds don’t spawn to frequently and are generally spread apart. Or for council good position would hit all 3.
As for divine star this would easily be much better than current shadow crash. Make sure you get a few dots out and then throw a star at them, For M+. As for raid it might not be bad on T-Swift but the adds roots still due to quick.
