User blog:Galeforce's Wrath/What units to raise?

So, I started a new game a few weeks ago on my phone (for some reason I don't feel that my lvl 141-or-something account on my tablet is as fun anymore) and so I'd like some recommendations on what units to stick with and which ones to not. ( I tried for a Juno-Seto but had no luck... but I got a few units anyways. ) Here's a full list of my units:

3 Star:

Elimo

5 Star:

Ivris (A)

Kagura (A)

Bestie (O)

Signas (A)

Sareas (B)

Themis (A)

Will (A)

Carrol (O)

Kanon (L)

Zephyr (G)

Rineth (B)

Drevas (B)

Charla (A)

Sirius (G)

Rhoa (B)

Aurelia (A)

Fadahl (L)

Julius (A)

6 Star:

Fei and Fang (B)

Feeva (G)

Dilma (B)

I'm going for any units to raise that are currently good now, as I'd hope that they won't be too outclassed by the time I get to higher levels.
