I recently asked this question on the Deck of Many Things which was closed as opinion-based. I would like to revisit the topic and ask for expert opinion from a different angle.
To avoid as much controversy on the main site as the other question caused, I would like to submit the for review here before posting it (or refraining from doing so).
I would like to ask a question along the lines of: "What concrete negative consequences does the Deck of Many Things usually have on a campaign causing its reputation as campaign killer?"
I feel like this question is not opinion-based but would like to hear your takes on the matter - that's what this post is for. Is that question stackable?
