Discipline has been one of the top healing specs over the years, but Battle for Azeroth has seen a drastic decrease in the amount of people playing it.
Battle of Dazar'alor has been out for a month and it seems to be treating Priest healers pretty well.
Despite getting nerfed to heck in patch 8.1 -- which sounded more dire than it actually was -- Priests are still in a good spot this tier.
The first major patch update of Battle for Azeroth is coming in a couple weeks.
Priests are unique in that we're the only class in WoW that has two healing specs.
The moment we were waiting for finally came, and Battle for Azeroth launched earlier this month.
We've got a week left of Legion but that doesn't mean there isn't time for more class tuning.
