It's dangerous to go alone, take this!
I feel as though the current summons are just placeholders. Some thought went into their design, but they're polarizing compared to every FF summon prior. Even summons that aren't out yet (FFXV) crush XIV's summons.
Replacing the current egi models with miniature/chibi Puff of Darkness/Succubus version primals would bridge the gap between old style impact summons and current
Using Ramuh's mini-me Arbiters as an example were he to get his own egi, a combination of Primal and element can look pretty good. I don't mean Eos/Selene sized, more the primals scaled to egi size and then altered to fit. The primals have very tangible personalities, that don't translate to their egis. Changing them like this would allow SE to give egis their original's personalities and make them a bit more interactive instead of just a third of my damage that I have to babysit
