Why are SMNs not getting new Egi?

[Claviusnex]

A Phoenix Egi which already exists in-game (never seen it outside of its name on the enemy list) would be cool. Lower damage than Garuda-egi, but perhaps and maybe tied to a trait, a sort of auto-life ability for the summoner so if they die, the egi may die too and revive the summoner and put that summon ability on a cooldown or something to prevent a theoretically immortal summoner and keep it as a sort of oh shit button.

I like the phoenix idea. I would also have no qualms with it making me immortal.
