If the goal of ‘Elastic’ group plexes was to encourage people to group up, a more significant number than 5 should have been chosen.
Ideally 10.
5 is too small to cultivate the habit of looking out for people and incentivize people into forming groups, they especially won’t do it for a measly 25%.
With 10, you had the space for bigger rewards, bigger incentives, and more capturing challenge on a daily basis.
That and it’s highly probable that people will find ways to solo those 5-plexes, entirely defeating the goal.
I would advise changing the size of those places to 10 and increase payouts to 100% so that the effort of finding people is more properly rewarded.
