I ran a game using this file. It was very improvisational, and I don't think it's suitable for every group. However, we really enjoyed it and it was a lot of fun. The structure really lent itself to a game with very little preparation, and it fits very well with the themes of Waterdeep Dragon Heist. I liked it.
I think it needs serious beefing up on how to create complications and how to use them. I think a lot of GMs would need help in that specific area.
