Thank you for the very detailed explanation! The design choice you have made makes perfect sense to me, and now I'm even more excited for this game. I didn't think that was possible. I'm all for the separated disciplines route. Does that mean Tzimisce will go back to having Vicissitude?!
Perhaps for your next dev video, you can focus on disciplines and how they function in-game? I mean, I understand now how it works based on your explanation, but it would be awesome to have a video showcase, and I imagine it will hook even more fans into the game.
