Honestly I've been largely a DPS player and I think there needs to be another healer too. Dancer seems likely given how much demand there is, and Geomancer seems like it has a strong likelihood too. Would like a kind of dark healer tonally as contrast to White Mage, Scholar, and Astrologian. It would also loop healers in alongside edgy DPS (dragoon, black mage) and tank classes (dark knight) but I don't have high hopes, at least for this expansion. Do think it makes sense for there to be another healer and a pause on DPS personally regardless, hope whatever comes out is a lot of fun!
