In my opinion so far, this is a really masterful mini-campaign setting, it gives a DM dozens of ideas, and then leaves up to you, if desired, to modify them to make them fit together in unique ways. And this caters to my style of play anyway, and it's what i did with Lost Mine. One downside is that you have to read the HELL out of the campaign book and make notes, so you're not really saving time per say in the short run, but in the long run you have a more comprehensive arc that fits together, and that is something I'm not really good at and I'm glad to have that arc laid out for me.
