That is actually almost my idea:

Use the capped tome to unlock gear, but buy it after that with the lower or even poetics right away. Crafted gear would not loose its value as you still can only get one piece at the first week or first two weeks. But you would not be limited that much anymore.

Yes, tome gear is "special" and should be worked for, but lets face it, all that is out of the window the moment they deceided to flood our retainers with last patch tome gear now...
