With the changes to threat, and with stances starting out activated, I feel like Atugia should have her Ancestral Judgement changed (or, changed again, since it previously got changed from shooting an enemy with some spectral bow). Ancestral Judgement does have a use case in situations where an enemy has an aoe attack, and that is a fairly common one, and the skill has some pretty significant uptime. That said, because of the removal of random targeting, it's now only useful in that situation (or if your damage dealer overpowers Atugia's threat generation, but that's just a skill issue), and since Atugia should have the highest threat on your team, it's pretty much useless against any power which only targets one person. Essentially, I think that it should have some benefit for Atugia herself. She's funneling damage onto herself, whether because of threat or because of the AJ shields, so she's taking all of the damage, and I think AJ should do something for her on top of the damage funnel.
Though also, aside from that, the shield it generates seems to have an odd scaling. A level 2 Atugia's AJ provides her allies a 39 hp shield, and at level 6... it's 43? Even if you don't change it so that it provides some effect to herself aside from the ally protection, I think the shield should probably be increasing by a lot more than just one hp per level. Though my level 4 characters have her giving a 42 hp shield (43 with the Black Mage's Arcane Attunement buff active), so. I don't really know what the scaling is like, but it feels like it's probably too low.
