Thanks for the link. I took the survey.
I put down that I want the MM as a DM only book and that I want Demons and Devils. However, I didn't have enough room in the comments to put down that I don't care about Primordials and deities and want them in their own book. I used the comment space to tell them what I like about the 1e MM (having the demon princes and arch-devils), 2e MM (ecologies) and 3e MM (ability scores and ac broken down). I also told them that I liked third party books like Green Ronin's Advanced Bestiary, Silverthorne's Book of Templates, and Betabunny's Predators. The template books not only made it easy to modify races and monsters, but, when applied to animals in Predators, one could create new monster variants of animals, duplicate several MM critters, and also have real animals populating the setting.
