Players Wont be able to summon Ifrit

[Reika]

That the storyline that only one avatar can help the city but if you follow the storyline we pretty much ask the other avatars for help and ifirt get mad at least that what it look like. they be a class which summon them and they can ask each one to make a pack with then but it be a chain of quest at least what Tanaka said but who knows what yoshi-p does for all we know it make it easy you can do in 10mins

And THIS is probably the reason for the Ifrit battle quest: Asking another Eikon/Primal for help instead of ifrit. He has a fiery temper, yes?

I wouldnt want Ifrits help anyways, I would choose Leviathan or Shiva.
