I think they should remove the Egi idea, why giving us Lowered primals ? Give us High Elemental/Holy Spirits and Beasts instead !!!

Leave the Primals to the beast tribes, they're like Racial Deities in FFTA, they shouldn't be able to be summoned by a summoner, the FC summoning one is a good idea though.

But give us full entities like Carbuncle is, it's not like there's not enough summons that exists through all the FF series !

Why not giving us let's say, cerberus as a fire pet ? Ixion as a lightning one ? Valefor as wind, and so on...

Those summons would be a less powerful "life-form" than the primals, but would still make us feel like summoners, because they would be complete, detailed, and maybe as big as a mount can be ? We don't need it to be bigger than the current mount !

We all know it's not a graphical/technical restriction, when we see the amounts of Magitek armor wandering everywhere...

I think they should tweak the lore a bit, and give the summoner real summons, we don't need the formal Ifrit/Shiva/Ramuh/Titan etc. summons, they have so many that they could give us instead !
