If you’re not going to do QoH yet then I’d hold off on Freya.
Freya needs other minion hero’s to be any good…
Preferably with high attack minions so that she can generate genuine sting from them.
Low attack minions like Telluria’s for example get more powerful but they’re still not going to damage much.
Inari obviously can give you attacking minions, but then you’re not reliably able to get them on the field without Puss - unless those foxes pop up, Freya doesn’t do much.
I’ve played with multiple minion teams and my honest opinion is I wouldn’t bother with Freya if I didn’t have Puss… With Delilah and Telluria I get a minor difference.
With Puss it becomes truly minion mayhem.
No rush to decide, though… It doesn’t hurt to take time to think it over.
