My original intention for this suggestion was exclusively meant for custom scenarios. I think it could be also extended to regular adventures, we'll see. Suggestion: After the first time completion of an adventure module, let the player rate the adventure on a 1-5 star rating. Collate the data for all players and either pump it thru the api, list it on the Card Hunter website for sharing. Or an in-game rating list in the SP map. Idea is to let new players sift thru adventure difficulty and be mentally prepared, so to speak. I believe this would also be useful when the level cap is raised. Hope it helps. Thanks for reading.
I'd say allowing a re-rate of adventure to disallow rage-ratings would be good, even if it requires a completion to rate. Sometimes you change your mind about what is good design and just bad luck, after all. Otherwise a good suggestion - would probably be of interest to BM as well.
