I agree that the Anathematic model doesn't need to change. And I would probably not like the new version, because to me, every drone/tag looks too much like the others. But fluff wise, the Anathematic is a buffed Charontid. So it would be normal that these two look like each other. "The Anathematics are Charontids comprehensively modified with concealment devices and advanced camouflage systems."
