A very nerfed and neutered version of it maybe.
Still has Surge of Darkness in MoP and WoD and WoD we had Clarity of Power as a way to also be more mobile and bursty.
I would say the aspects that made Shadow fun in any iteration of the game seems to be removed or heavily nerfed.
I mean I would be shocked if this is what they intended, I am pretty confident that they ran out of time due to people leaving based on the recent news of getting people to return to the office.
So pretty sure there will be a lot of changes/updates/reworks in the next round of class updates. Perhaps even some hot fixes if the misery of Shadow Priests gets loud enough to not ignore lol.
