Way, way too much work for very few gains. I mean, think about this logistically. If they were to segregate tomes into individual jobs, it means we now have 13 potential sets of tomes instead of 1. If they don't lock it, and they have it as a general cap there's still nothing stopping you from gearing one job faster than the other, and it gives you an unfair advantage simply by having multiple jobs.

Furthermore, no one really wants them to start job-locking accessories. We need 2 rings per job as it is, that's 26 rings taken up in our inventory space, not including crafting or gathering classes. Not to mention having them would be yet another thing we would need to save tomes for separately, which is just needlessly adding to the grind.

I'm all for them increasing or even removing the cap some day, but some of these suggestions leave me shaking my head in wonder.
