Again, late to the party, trying to grasp the concept here. Perhaps I worded my post wrong. My main concern is that we don't have more than 7 base classes with this system. I understand your proposal as posted in the OP. The specialization isn't a new class, it's an augmentation to the existing ones. Once my GLA is R50 though, I can freely swap between PLD and DRK. We get 14 specializations for the price of 7.

If you outlined something about new classes, I'm not seeing it. Adding new classes is including 2 specializations for each of those, again, a huge task to keep everything balanced while trying to maintain uniqueness.

Zaene is resonating with what I'm saying here.
