In my opinion the Necrolord Covenant ability “Unholy Nova” Was so good and fit the aesthetic really well of shadow priests. I really want this ability back to boost SP dps cuz right now shadow priests are so bad. Not only that, while a lot of other classes got multiple covenant abilities into DF, shadow priests got mindgames and mindgames right now is nerfed down to hell so it doesnt matter. Now that blizz is more open to adding more class fantasy things and listening to the community more, it is a great time to make this suggestion. Not only can this ability affect and help A LOT in PvE/M+, it can also help PvPers Very very much since its a instant dot. If Unholy Nova was added back to Shadow priests, it would only be in the shadow talent tree, not disc or holy. Please blizzard, This would benefit all shadow priests whatever content theyre doing and it is such a good ability !
Here is the ability for people who dont know what it is.
Instant 1 min cooldown
