Adjust weekly gear and tome limits from per player to per role.

[ShiroeTengoku]

The simple(st) solution is just raise the cap to 900 a week. It doubles how quickly you can purchase gear for all the jobs, but also lets you accelerate gear even if just doing one job. Instead of capping one week, then rushing to cap a second week for your chest or pants, you can just do the one week and get your piece. Assuming a person is just buying tome gear, and only tome gear (due to not Savage raiding, blah blah what-have-you) costs 4,635 tomes. Even with a cap of 900 a week, you are still dedicating 5.15 weeks to a single set (Fending/Healing/Casting you get it). So if you kept that pace for the 7 sets that exist and the caveat of 5 sets of accessories, that's just over 32 weeks or 8 months, which is close to an entire raid cycle.

EDIT: Decided it would be beneficial to put the math and costs here, in case someone takes issue with the numbers.

Head/Hands/Feet are 495 at 1485 (3 pieces)
Body/Legs are 825 at 1650 (2 pieces)
Accessories are 375 at 1500 (4 pieces)
