I would rather not focus on the negatives of our situation. Why go back to being organic when we can have something else entirely. A middle ground where we get the best of both worlds. You can even die if you like. Cryptek is the option most likely to make it happen.
Beyond that necron science is amazing. If anything it is underutilized in many places.
But it's not middle ground. The Cryptek craves godhood, transcendence, I really don't think this is the type of person who would be like "okay, it was fun but I think I'm going to let go now". The Cryptek doesn't want anything resembling mortality, the previous state of the Necrontyr being.
Also, I don't see The Cynic as purely negative, most Necrons want their organic forms back, the only difference is that, The Cynic thinks that Necrontyr wanting more was mistake in the first place, that their people should had learned to let go and accept the natural order of things, which is both interesting and fitting for a Necron Overlord.
Also, in general, somehow down-to-earth noble, who is self-aware about their current situation, and has to deal with the cesspit that is Milky Way is just cool for me.
Also, I very much dislike QM favoritism. Boredblues really shouldn't have done it. No problem if boredblues just said that they like the plan and would be happy if it wins but trying to insure that the Architect plan wins by promising special reward, that no other plan will get no matter how well thought out or narratively fun, was just horrible decision and very unfair.
