For some reasons, I'm not too fond of it.
My main reason is, it removes some of what little game elements this game had. How? It makes the game passive, almost as if I'm botting. My girls are clearing a map as I'm typing this, it's just a matter of starting a map, tab out, and return a few minutes later to check what they farmed for me.
If you ever get bored with this game: I'd suggest you try to run a few maps with autorun switched off for a change.

On top of that, I still have a suspicion that the random nodes aren't as purely random as we think. They may not direct the girls in the direction we suspect, but that doesn't necessarily mean they're truely random, but more imply such.
