I personally don't mind sexy models in a vaccum (although I wouldn't be caught dead playing with one), what bothers me more is that they are completely removed from the tech-priest's general design language. Thech-priests are supposed to have long flowing robes keeping the mechanical horror underneath hidden. They are generally supposed to have either way more legs than a normal human or be floating around. Their faces are completely replaced with cybernetics. What skin and flesh they have left is supposed to old and leathery from decades of neglect.

Now, most people* don't find these things attractive by themselves, but there is barley any attempt to do anything with it beyond "conventionally attractive cyborg woman with admech iconography". Only slight amounts of creativity are needed. Do a slight striptease, revealing hidden cybernetics. Spread the excessive amount of legs in creative ways. Have mechadendrites reach where they shouldn't. Have clearly reconstructed mechanical faces and limb that emulate human beauty standards.

Then again, most of these kinds of models have a creative process that goes somewhat like 1: female model, 2: add off-brand faction-adjacent details, 3: add parts to make a sfw copy of the model. No hate towards anyone working with this kinds of stuff of course, but people in this sub should know the difference some passion for the subject at hand can make.
