She has no room in her inventory for Void Staff or Rabadon's. She's too reliant on CDR, Rylai's, and general defenses to justify picking her.
I'm legitimately worried she won't permeate the scene. She received no attention on PBE forums, despite just about every poster claiming the same things:
Cooldowns too high
Limited chasing power
Absolutely decimated in melee range
Spiderling vulnerability and too much of her potential damage invested into them
I understand you'd rather release her slightly underpowered, especially considering the Rengar debacle, but her problems are about core playability issues, not just scaling.
