With no elemental wheel it would be very difficult for a developer to balance all these Egi and keep their play styles unique (just like this multiple Trance idea) One or two will always out perform over the rest, and like it or not that's the fact of the matter. When you are developing for an MMO sized game things like that have to be sacrificed/compromised for something more economical in terms of development time. The Egi glamour system is that compromise, it's either we get one or two more unique Egi play styles, or a whole host of new Egi that fit into one of the 3 current Egi types...
The Egi galmour is not a bad thing at all, for example when we unlock the Leviathan, Ramuh and Shiva glamours they would most likely not only change the model of the Egi to that of the chosen glamour but also give them a whole new animation set and visual effects. The only thing that would stay the same is the programming of how that Egi works in game play. But it would actually look and feel like a brand new Egi.
