I always kinda liked the poor egis, thought of them as a kind of aetheric marionette that both simulates and mocks the original primal. I wouldn't be against maybe more details in the egi model, like maybe some little glowing eyes and maybe a more feathery look to Garuda-egi's.

Honestly I'd be happy if SE just made them look more crystalline and transparent to go with the whole aetherial manifestation of a primal deal.
