I'd like to suggest speeding up REPEAT, Legacy Relics, and also adding BLU Relics

Some ideas to maybe go along with this (I like the OP):

BLU's canes might come with special effects, since it's a limited job the balance issue of doing this to normal jobs is not as important and you can still glamour if you don't want one passive but like the look. For example Ramuh's cane, may have a chance to strike a random enmity'd monster with lighting each time you use a magical spell. Double % if that spell is lightning element (So even if a thunder build isn't the most damage it would certainly be fun to try ). Cane that has a chance to duplicate the last physical spell. Debuffs the target is immune to turn into a generic DoT instead. Etc, etc.

Another idea might be some neat Beast Tribe quests (including allowing them all to scale up to the current blue cap, the rewards updating per your level). Meanwhile there might be new blue skills and content around beast tribes, even to the depths of maybe adding a beastman arena, like the FFX monster arena. Such an arena would be akin to the Carnivale but rather than so strictly constructed around specific spell gimmicks it would be a more general challenge (like if you don't have X Y Z in quite a number of Carnivale events then there is no point in doing that event, as it was strictly designed for that spell).

May think of a general challenge similar to how Diablo 3 works in the late game, where until much later (late) game you can approach it with a competent but many options build and be successful (VERY late is far more strict but many many people don't play to that level).

Then new things to spend your tokens on for each tribe, which could be things to build relics, staffs, maybe purchase passives like a FFXI / Diablo 3 horadric cube system, or even work back into generic relic systems like for 100 tokens you might upgrade the Slyph area to have a fountain. The fountain allowing you a free quantity of light (or perhaps at beast tribe token cost, allowing players to not do Totorak 500 times). The Ixali you can upgrade their ability to go out on adventures, like FC do with their airships, and you can then have them complete sections of your book for you like a squadron mechanic. An idea that might be nice to reuse old tokens as well is using them to invest back into infrastructure of the tribe (or even other tribes). Such as spending 50 tokens so the Kobold have a fancy forge. Because beast tribes have a limiter you can be both generous and not hyper-accelerated on such relic concepts, and because the relics such ideas would work for are really old it might just be more fun to do it this way lol. (Like I said rather than farming light by spamming the same thing OVER and OVER, maybe you just do your beast tribe cap occasionally making big progress each week- but not as spammy, especially might be more interesting for getting players to try the old content and if all the tribes sync their quests).
