Quoting a blue from a previous thread hope that is ok.
From what I understand the nerf was mostly for AOE damage but they changed it as well so that procs can trigger the light explosion which brings it out neutral maybe a net positive if you get procs during wings from empyrian power or DP.
What has happened is that although the single target nerf wasn’t a whole lot in overall damage, as a result it is almost always never beneficial to stack 2 or three traits of lights decree since the nerf is getting compounded every time you stack the trait.
yes most of the damage comes from an extra 5 seconds of wings but with the explosion nerf it is now better to take weak traits like avenger’s might over a second lights decree trait which doesn’t feel great especially when there are generic traits that stack very well together that many classes have access to.
As well it seems like it was originally intended for ret pallys to be stacking 3x lights decree due to several pieces in the raid and mythic plus vendor carrying the trait, and now it seems like that design intent was broken with the single target nerf.
I think a way they could have handled the AOE balancing without having single target to suffer is have the target from the explosion cap at 5-10 targets and over that limit the damage would be spread evenly, keeping the single target explosion the same or could even raise it this way to be in line with other generic traits like treacherous covenant.
This way it would once again be a strong trait to stack 3 of like it was originally intended throughout the raid tier and in m+, since so much gear in the raid has lights decree as an option.
This does enlighten me a bit to how maybe some azerite traits could get a little more love in the balancing department. Some traits are very strong when stacked to 3 however some you only want 1 of almost always.
Obviously the challenge is creating a trait that when stacked 3x isn’t too broken but still feels good running it multiple times.
I don’t think the current state of how handling lights decree should be considered final and hope that if there is another round of balancing done that the developers will consider somehow making lights decree a stackable trait single target.
(ps: in arena’s lights decree breaks my hunter’s frost traps maybe it could get the avenger’s shield treatment and not break cc unintentionally <3)
