All right - I finished it last night myself and while I can totally see where you're coming from, I think it will definitely get much better in terms of femdom content in the subsequent updates so I'll give a more optimistic perspective for everyone who loved MotF! (there will be spoilers ahead for Mistresses of Hell, so play it first if you haven't as you should be able to finish it in about an hour or so - just bear in mind that you have to keep losing to the scout either 5 or 6 times to advance submissively, not dominantly, towards the content that will come in the next update)
Obviously this is a very different game from MotF, as the submission battle mechanic, which I loved as well, is gone, and if "keep losing to progress on the sub path" is too off-putting of a game design choice for you to enjoy this, then unfortunately you're probably right and won't like thie game...

I made a case above as to why I think MC will become more submissive and tolerant, as well as why there will definitely be much more femdon content in later updates, but I don't think that game mechanic, of advancing on the most submissive path only via succesive losing, will go away.
If characters you loved in the prequel might bring you back, even though you said your favourite mistress was the Bargatian chieftess, I think there's a good chance that not just Piroa, but also the Vampire countess and her 2 blood-daughters might show up, as her residence was also in Korluntine where the current events of the game are happening...
For everyone else reading this, I think this is definitely going to become a great femdom game with a beautifully-woven narrative, and I don't think CrimsonGrey will ever write a maledom path even if you play the game by defeating the succubi (most likely it will be a path with a slower descent into potentially lighter submission, but not a maledom one), but if what you're looking for is strictly femdom scenes or plenty of plot, there isn't very much of either in this first version so it's probably best you wait for the next update before trying it out!
