John,
Please change the chronicle to reflect the guiding mantra of the Pathfinder Society, namely: "Explore, Report, Cooperate"
There needs to be a community-building feel from Specials, not a PvP-Lite passive-aggressive favoritism that encourages 'chronicle-fishing' and 'mandatory option paths'.
For those who don't do the particular arc in question, if another team covers the difference, then that other team's members may benefit from teamwork on something THEY didn't reach.
I hope going forward that the community continues to be built, and that the careful consideration of ALL members of the community, including those who volunteer their time in lieu of GMing to make these amazing Specials work.
Again, not seeking a chronicle, but rather understanding that volunteers are working to make the Special go, and 'just GM a slot' is not a valid answer to when they do eventually get to play the scenario.
May wisdom and understanding help balance the needs of the campaign and the community, that the community as a whole emerges stronger and healthier for the experience.
