What to Level Up Next - 2 x Aegir's?

I have maxed out ;

Wu Kong
Kelile
Tiburtus
Kiril

On Deck to Feed is;

Azlar
Aegir x 2
Sonya
Li Xiu
Boldtusk
Rigard
Boril
Chao
Triton
Proteus
Gormek
Gladerius
Agwe

Do I feed both Aegir’s ? Is there any value or practical use in having 2 Aegir’s ?
I am thinking either Aegir or Proteus. Both are ranked/graded as ‘A’ level heroes in Anchor’s Guide

Thoughts and Feedback welcome

Go for Chao then Triton
Later get up your Aegir.
But I might not get him more tha 3^70 a better 5☆ could earn the telescopes

Definitely Proteus. He outperforms any other 4*s and is cheap to max.

If it was me, I’d choose this defense team:

Kiril, Azlar, Aegir, Proteus, Sonya
