FOMO rewards are something I oppose on principle, like for PvE rewards are not tied to a timed limited basis, you can still do ultimates, clear them and get their respective rewards, and PvE in FF is far more polished than PvP. In PvP not only you have to deal with things like random and uncoordinated teams, lack of a per-job basis rank, the horrid netcode of the game, not to mention cheating and other things that have gone unaddressed for entire patches (hacking, win trading and so on).

If you really want to attract people to Crystaline conflict and PvP for that matter, glamour rewards should come on a more consistent basis, same with mounts. Those who want to go for ranked should keep the same rewards as there are now titles/frames/trophies. But SE seriously needs to add more items in exchange for trophies, and make at least 1 glamour armor set per season and series
