More egis

[Exodus-E]

I personally want EGIS gone for once and for all and just make the rest of the Summons like Bahamut, Get into battle for 15 seconds.

NOT gonna happen.
Egis are deeply rooted into this game's lore; so much so that changing them from the ground up at this point would be a huge task for the development team.
It'd be like asking for ACN to not summon Carbuncles / SCH to not summon fairies anymore.

In fact, that's the whole reason why we want Egi glamours: so we can finally get the ones we've been missing post-2.0 (like Leviathan, Ramuh, Shiva, etc.).

Sure, we have Dreadwyrm Trance (and "Summon Bahamut", which is effectively an extension of that) as an alternative.
But like it or not, SMN's main form of summoning are Egis, ie. "essence" of Primals.

EDIT:
And speaking of lore, they will have to find another way (ie. new side-quest) to justify us being able to summon different Egis.
The Carbuncle explanation from the ÄCN side-quest won't work, given that most of the remaining Egis have different aspects entirely...
