I mean, he's got a point. I don't remember seeing huge Ferengi dongs and a second set of boobs on Troi in TNG - ergo, no Gene "Perpetuum Mobile"* Roddenberry involvement whatsoever, thankyouverymuch. /sOnce you know Gene Roddenberry's writing style and the ideas he liked to constantly push, it's very easy to look at the TNG Series Bible plus the first 18 episodes (before he stepped down as Showrunner) and see who came up with what.
