Honestly, I think these maps are impossible for some classes? If you're a Dragoon or Monk? Good luck man. Might be about to do two or three of the variations. But I've encountered some (the one with the multiple bombs comes to mind) that are just stupid. Each blow up for 1500-2000 damage and there are six of them? Even with a chocobo healing you, you're dead. No two ways about it.
That being said, this grind is better than atma and animus, I just don't like the idea of calling for help once a day. It's annoying to do that.
