Just level the waifus you like.

Thinking about being optimal would ruin the fun.

Camellia was not worth grinding? Who said that? If I have her she would never leave my squad T.T

Anyway, this game does not need the "best" units in terms of stats & skills. Just level and evolve them and you can clear the game with no issues. (At least based on all the maps we have so far). Ultimately, just play with whomever you fancy and don't be bothered with numbers too much.

Also, don't be afraid to evolve the lower rarity girls as well. They are easier to reach the level required, and the bloom dragons are easier to acquire as well. Their evolved forms can hold their own just fine.

I did that in other games similar to FKG before... It's fun and all, until your units gets raped at every single node in an event map o.o

Alright. So keep and grind Camellia, along with my other relatively-rare girls.

Are there any high level girls with crap stats that would be better for me to avoid if possible?

Ty for all of you guys replies btw

You CAN'T avoid anybody if you gun for "rare" (read: premium) girls anyway. RNG giveth what RNG giveth.
That being said, it is the game that can be cleared with silvers and event golds, so don't worry about performance much and enjoy your time with your waifus.
