Could you elaborate a bit more on why you think they got nerfed?
The opposite is the case, they were made ridiculously easy to get and upgrade. As RasAlgethi pointed out here, you can unlock the secondary in a bit more than 2 hours.
Certain ones were nerf'd a bit (Enforcer is 15%, Bane of the trapped is 15% at rank 0). Certain ones got buffed (smite gem starts at 2000% weapon damage, the Poison and Bleed ones also got buffed).
Or do you think they won't go live in its current iteration.

They're still just balancing the gems out.
