Keeping it part of the casual content and putting in what you ask for may not be possible.

Leves are supposed to feel casual, if i'm understanding the point of them correctly, as they are solo-able, can be done with very small groups.

rather than start them all at once, I like the idea of starting them at the end of the one you just finished from the node.

I'd also like to see an option to teleport back to the town they started in, and not just back to the crystal.

there is just an excessive amount of running around imo
