The Beast. I know it's one of the most important part if the game, but I tend to hate everything that removes agency from the player. It's also kind of a contradiction for a vampire game : i know the point of the game is to keep your own humanity and all that, but still, it's a game about vampire, you'd think you could play the bad guy once in a while, go full dracula or use your powers to go rob banks or something, but doing that will tank your humanity and make you frenzy and rotshreck all the time, even making you lose all control eventually.
Also, I think being close to your humanity...
