The standard answer is that if someone gets hold of your generation procedure, they can guess all your other passwords, and your future passwords too.

They'd still need your master pass phrase though? So the security is only as flawed as a password manager

With DPG, you don't have to use the same sentence for each generated password. It makes it easier and more user friendly, but it's not required. I could easily have two or three sentences and still be able to recall 400 or so unique, strong passwords.
