The player-moderated Ancient Cyclops list is a disaster.

[Castle2.0]

top 6 people must be at camp.

Same problem exists, but it pushes it back to #6. You're still churning tons of people who aren't there to get someone in the #6 slot who is there. There is no way to show the exclusivity of the #6 spot other than the list itself - you don't need to be kill a mob (that only you kill) or anything like that.

Who notifies #8 that #7 didn't show and #8 is supposed to move into the #6 slot? No incentive from 1-5, and #8 isn't sure who to ask.

You're putting in a physical presence test with no one to enforce. Does #8 need to be present to ensure if #7 isn't there that #8 will move into the #6 slot when it vacates?

If #6 leaves, does #7 need to be immediately on? Does he has 2 minutes? 20 minutes? 1 hour?

Then you're making it 7-8+ people need to be at camp, not just 6.

This solution just opens up more problems.

Solution: Keep your silly 100+ list, or have a hard-coded enforced list with AFK checks exactly like legacy items. No elf-litigation or Rube Goldberg'esque mechanics needed.
