I bet my all my Gil that Sage will just be a copypasted SCH that may or may not use its weapons in a similar way the "fairy" works.

As for SCH, i expect another attempt to remove Energy Drain and if they have been "zealous" enough, the Fairy will be completely gone as a Pet and just exists in the form of visuals, because lord forbid, if our healers have anything remotely complex on their part.
