Well, with this you could definitely say goodbye to RDM. Sages in other games are basically better versions of RDM without the melee abilities and are less durable. The melee of RDMs in FFXIV really is just tacked on.

So Sage, which brings buffs to both melee and magic users, would probably replace RDM altogether due to superior utility over RDM, who only brings a melee damage buff and raise. And if Sages, masters of White and Black magic, also get Raise then GG RDM.

Personally, from what I see here, for your version of Sage to not completely push RDMs out, they'd have to complete work RDMs (and I would have no issue with that as I feel the melee aspects of the class are a wasted opportunity).
