To be honest? If people are excited to play Sage and it creates a problem for a lack of Pure Healers, that would be great. It means SE made a mistake and haven't given the "pure healers" enough attention to make them interesting enough for people to play and adjustments might actually be made. Otherwise... meh? It doesn't really hurt or harm. It just irks me that they are forcing this dichotomy in the game when there could be more diversity on all the healers. Variety is the spice of life, as the saying goes after all. And healers are lacking a lot of spice right now... aside from Sage.
