I don't understand why people are still bitching...SE have confirmed they are working on a new Egi glamour system so either way we will be getting future Egi in one way or another. Also let's be real for a second, if said glamour system was to be implemented for the release of Heavensward with Carbuncle, Leviathan, Ramuh, and Shiva as new Egi glamours everyone would be loving it with no complaints....just saying.

I am sure SE would have implemented this into HW had they not had to essentially overhaul how the core job works in a way that works with the SMN's lore. They simply chose to prioritize this over the new Egi glamour system, which will be coming at a later date (most likely in a future HW patch)
