Even though you have reworded your original idea, I still disagree because all's you have done is reword it. You have attempted to make it appear as an altruistic idea to benefit the players who have no experience in dungeons and help them out, you and your friends will still be reaping the benefits of the exp card having the dungeon added onto it and be able to 'screw around' as you have said before. People lose exp in the dungeons and just right they should, they won't be as reckless and stupid if there are consequences for their ignorance and arrogance.
I would also like to add that in your previous thread (you know, the one you deleted because of all the negative feedback/criticism you recieved) you thought none of us knew what you meant by 'screwing around', we all know what it means and was one of the reasons you recieved such harsh feedback, at least this time you have attempted to veil your true reasons, thinly.
I think the moolah sale is a good idea however, it could attract funding from those who would otherwise not donate.
