I'll be impressed if they ever add those two. Coordinating NPCs enough to kill Facers on plates (or clear Doom, or deal with Verges), or dealing with the chimera ice/lightning could be a challenge.

Then again, I wouldn't have expected DD, either, with all the complications Ahriman might present. Can't wait to see squad target it to chase it down the halls trying to fight while aggroing everything else.

Actually, all three of those will probably present interesting new challenges to face with NPCs. Ahriman seems most prominent for DD, but Sirius also has a boss with a "don't target everything else" mechanic (zuu eggs), and Copperbell hard, all of those bosses could be difficult for NPCs to understand.

Hopefully the changes to squad behavior means they took this all into account and planned accordingly.
