Future of the Scholar (Helios)

And am I the only one who sees that Eos is not the way in the majority of the content?

You're definitely not the only one. I actually use Selene in the vast majority of the content for the game simply because Eos' extra healing abilities aren't really needed. I do still use Eos for Turn 5 though but I will probably make the jump to Selene eventually. Eos (imo) is the safer choice for progressing on new content, but Selene is usually better overall.

[Edit] I think I also would use Eos for solo-healing certain content (like EX Garuda or HM Titan), but even then I'm not sure it's necessary.
