"I don't like this feature, so obviously the devs made it as a "fuck you" to me."
Asking for support for competitive questing OR game master mode in single player is basically asking to play opposing decks in MTG alone. This isn't a "fuck you" to single player centric players at all, just expanding on multiplayer and delivering on a feature specifically detailed in the kickstarter. Go make some friends instead of complaining about how you can't do everything yourself.
