I do appreciate that the new opponents in CZs have phasing lasers, prismatic shields, and oddball stuff like corrosive missiles. Bullet spongeyness is a pretty low level dev response, but is consistent with engineering.
What I have always found weird in CZs is the targeting prioritization. If you accidentlly fly through the middle of the zone, you are swarmed. So, you spend your time peeling away the onion until the spec ops show up. Not awful, just weird. Plenty of other ally npc ships fly through the middle f the cz, do they get swarmed? Maybe, I haven't observed it though.
