how to easily add more glamour plates

[Rongway]

Glamour plates aren't connected to jobs in the first place, so your logic doesn't make sense.

The vast majority of glamour plate applications are via gearset link.

The vast majority of glamour plate applications are via gearset link.

That's irrelevant. Glamour plates exist independently of gearsets; being able to link them doesn't make them inherently linked, so OP's suggestion that we can get more plates by de-linking them doesn't add up.

Even if they were linked to begin with, I doubt we'd just spontaneously be able to "easily" get 20x the plates. The data still has to go somewhere and if they had that much extra available, surely they could give it to us in the current system too.
