Waifus to farm and grind with

[squidshavetents]

Yo guys.

So. It's my 2-3rd day playing this game, I have a couple of 5**, a bunch of 4** and a shit-tonne of 3** (picture of units attached). I was just wondering if I am leveling the right characters. I've seen someone say that Camellia was not worth grinding and stuff. So any specific advice on who not to grind through?

Thanks y'all
