Eidolons & LCs for the new Firefly Premium Team

Hello, everyone!

With the announcement of 3.8 and The Dahlia, I have decided that I will pull her.
She will replace Ruan Mei, and I have:

• Firefly E2R1

• Fugue E0E0 - LC R5 "Resolution shines as pearls of sweat"

• Lingsha E0E0 - LC R5 "What is real?"

My question is:
Should I invest in Eidolons or LC-s for my Break Team after obtaining The Dahlia?
