I've messed around with Shadow in a few RBGs and it wasn't using my T6 ability at all(?) I even tested it on a dummy and still didn't use it. Maybe I missed/checked a setting by mistake lol
Anyway, I'd like to see Psychic Horror added to the burst toggle and prioritized before DP. I see all the top tier priests use Psychic Horror (to lock them down obviously + our 4 set bonus) then DP a few seconds later on their kill target.
This is the main way you kill with Shatterplay at least (Mage/Spriest/Hpal) just throw a HoJ or deep in there.
If this is added, an option to "Silence Healer on Psychic Horror" would great maybe?
Overall, I think this would be a really nice and important update to make the spriest portion of this routine more viable.
I also mentioned to Cokx an option to expand the Leap of Faith logic for shadow: use Leap of Faith on a blinded healer/whoever if we are standing in Frozen Orb (it has an AoE debuff that can be tracked). This can also be extended to Polymorphs in dire situations but, I think breaking blind is always right.
Cheers!
