Adel seems legit though, Mitigator with a Heal on Spark and a spark buff and he has an Atk,Def,Rec down negation and he has some potential to synergize pretty well with Kanon.

And as for Savia, I'm not even surprised that she's a bit meh. But at least she has some okay improvements like spark resist and her UBB seems decent IMO
