People just don't vote for the dom path. I do polls on a regular basis and only few people want to see more dom content.
Actually, a lot depends on the developer and what kind of story they had in mind originally. Yes, it sounds like Captain Obvious said that, but I'll clarify what I mean. As I see it (this is purely my personal opinion), you shouldn't get hung up on the polls alone, if you yourself are interested in the dom theme, you should continue to develop it in parallel with the sub and switch routes. The difference is that the KG developer has never focused on surveys as a reference point telling her what to do next or what type of content to create.
She originally wrote the entire story and the story backbone itself was never once changed to favor one player group or another. Yes, at first the Dominant's path wasn't so pronounced (until about chapter 5+), but still, it was clearly and distinctly separate from the sub routes. And the result of several paths of MC development was a natural, wider reach of the game's potential audience, attraction of new patrons and quite high profitability of the game (and if we take into account that any femdom-oriented games are a priori not too financially profitable, this approach turned out to be quite revealing). In any case, it's only your game and only your rules. I'm not going to advise you on how to proceed. I am sure that you yourself know it better than anyone else. Good luck.)
