I did the latest chapter of the Night Fae story on my paladin. This time it was all about Bwonsamdi, and trying to retcon Vol'jin's decision to make Sylvanas the Warchief at the beginning of Legion. As far as retcons go, It was pretty good. Having Muzahela be corrupt allows Bwonsamdi to be the hero (well, as much as Bwonsamdi can be). Since Bwonsamdi is extremely popular, this works out well.
One interesting mechanical note is that if you've be gaining renown every week, this week you complete the covenant armor set, and are able to upgrade all the pieces to be better than regular Mythic gear. That seems like a pretty good curve for more casual players who do not group.
On my priest, I got some more renown and did another chapter of the Maldraxxus story. Maldraxxus is very focused on the current Shadowlands situation, with quests involving first Bastion and now Revendreth. It's quite different from the Night Fae who are focused on finishing up existing Azeroth stories like Tyrande. I think I'm now one chapter away from being caught up. I might actually be able to catch up if I finish the 1000 anima quest. Not really sure that's going to happen.
Mechanically, I've been putting all my priest's anima into upgrading the covenant armor. It's worked out pretty well, with most pieces being around i177.
Also, I did the second layer of Torghast as a priest. I underestimated all the Psychic Scream powers. I was avoiding taking them because using Psychic Scream on trash just meant that they ran away and came back with friends. But it turns out that the final boss can be feared! So those are boss fight powers.
I still think that the majority of priest powers don't flow very well. Many of them seem way too niche. Part of the problem might be that very few of the powers are spec-specific, and most seem to be class-specific or more general instead. For a class where a specialization like Shadow is very different from the others, this causes issues.
