Are the moths too weak? Are the mega fiends mediocre?

I would love to hear other people’s opinion on the moth family in general. Not just one of them but them as a whole.

I feel like satinpimenter is great, mortewitch has a place…but the heroes who just summon 1 mega fiend…ummmm it sorta feels like a 4* ability that sounds super cool, but in actuality it’s fairly underwhelming.

Am I off my rocker here? Do you know something I don’t? Please discuss!
