There is no perfect way I guess. If everyone gets all items then people are complaining that it is not rare anymore and not worth something, also they are not proud of what they have then. If it requires some work for getting the items then some people complain about that too x-x
From what I have seen most groups had an average level of 30-40. The monsters in the xmas castle change their level dynamically based on the level of the players, so that also less strong players have chance.
We have made 21 scripts, several new locations, made up an interesting story and also a funny end boss. It's not perfect, but we can learn from that and improve things once we do such a quest again.
The recipe for doing the yellow stone is normally set at 100%, there are several reasons why a receipe can fail so I am not sure why it was failing several times for some people. We will probably improve that in the future so that quest-recipes always work, to make it less frustating. But besides that the quest also contains stuff like finding the good location, doing the good thing in the right situation, using different tools.
