They havent said anything other than when they nerfed the crystal stage it didnt feel like it was time to nerf the next stage yet. My guess is they will wait until the release of the next step. While not exactly a nerf the moogle beast tribe kind of eases it up a bit allowing the purchase of 1 item every 3 days (1 every 2 days at max rank) instead of 4 days unlike the old world beast tribe quests or 1 every 6 days like the gnath/vanu.
