Player-piloted Afflictor is still overpowered.
Harbinger is better than it was last release, but still not good enough. System is too crippled to be of much use. Basically, an extra-large Vanguard.
Doom still needs Systems Expertise to be great. It is too heavily reliant on its mines.
Ziggurat (with Phase Anchor) is still overpowered, but the change to IPDAI requiring s-mod to alter small weapons (IR PL, Rift Lance) means less effective OP (when you need every OP you can get for Omega loadouts) if player wants to use them for ePD+sIPDAI shenangians.
