This fan-made feature is already driving a noticeable increase in Illuvidex trading activity.
An official leaderboard—either in-game or integrated into Illuvidex—would likely amplify that effect. It doesn’t need to be perfect. Ship it as beta and iterate later.
The core value is simple: status.
Collection builders are highly motivated by recognition. This is why I supported the Illuvial Tree proposal—not for all the extra rewards, but for the collection leaderboard itself.
They’re already calculating collection power, so building a leaderboard on top of that should be straightforward.
This is low effort, high impact.
