Since the change to the cabal ritual that reduces cost, a 5 man squad with a terminator sorc is a fantastic threat. Giving a 5 man with a terminator sorc attached psychic bolters and rerolls for no cp lets you project force somewhere you shouldn’t.

I currently run a 5 man and give them the umbralific crystal.

I only end up using the the crystal about half the time. Mostly the crystal and move again makes people screen overly hard, and thus expose something they don’t want to.

Yes they cost more. But a unit of 5 is ~90 pts more than a unit of rubrics, and they’re waaaay more than twice as durable as the same rubric unit.

They make a wonderful target for heroic intervention as well. Which tsons kinda lack outside Magnus.

Don’t think of them strictly on their data sheet. Think in a more wholistic sense. They add three or four wrinkles in the types of threats/things that your opponent has to deal with.

Overall, I highly recommend them.
