Let's forget about the faults SMN may or may not have and focus on something good. Future Egi!
So now we are so familiar with the current trio of Egi (Ifrit, Titan, Garuda) and the Heavensward trio (Leviathan, Ramuh, Shiva) looking very likely. I wonder what new Egi will become available beyond this point. Beyond Heavensward and how each one will play/differ from past Egi.
Obviously a number a of new Primals have been revealed for Heavensward (Bismarck, Ravana, Alexander) So can we expect these to be the third trio of Egi? Or something totally different? After all there is also a couple of ARR Primals that could be worthy candidates (Phoenix, Mog). So there is definitely a lot of options regarding future Egi. But the question is, how much can they really differ from each other? Perhaps we will start to see Egi that have a greater focus on support/utility, a Phoenix Egi would certainly be a good candidate for such a role. Perhaps an Alexander Egi could also work in such a manner, along with a tanking focus much like Titan. Of course we may see a support/utility focus in either Leviathan, Ramuh or Shiva since this new trio will need to bring something new to the table also.
There is also the question of Elder Primal Egi (Bahamut, Odin, Belias) and what chances these have of being added to a SMN's repertoire.
