Hadestown - Persephone was Featured vs Eurydice?

Not to keep this going - I saw the recent posts about Hermes/Hades when I was looking to see if this had been discussed – but I feel like Persephone‘s part was so much bigger than Euridice’s? Of the five main cast members, she had the smallest part. I just saw the pro shot and her performance was amazing, but then I thought all of them were, with Orpheus being the weakest.
