I cannot imagine them stacking REVIVAL!tic either, because if they do, the tank is going to be unhealable pretty quickly and taking a tremendous amount of damage from the (dispellable) DoT. Also, since their health reportedly scales based on the mobs' health, this is going to make Fortified even more of a fucking slog. Hopefully they don't trigger Bolstering either because that would be a catastrophic shitshow in the later waves.
That said, I fully expect them to trigger both of those things on the first week those affixes come around because Blizzard doesn't think through or test anything prior to go live any more.
I suspect this one's going to be adjusted A LOT in the coming weeks, because right now it seems to further lock in a few classes as being ideal, and there's a lot of really shitty interactions here. We'll see how it goes in practice. If they're fairly burstable, it won't be that bad (except for the first week of every affix when they trigger things they shouldn't), but if they're at like 50% of the mob's health like I'm reading, that's going to be a real bad time.
Sounds like Kyn may have to become my Mythic+ main for the AOEs and stuns she has vs Pira.
