i mean, that's a thing. towns, individuals, skills, duels, trade skills, a lot of that already exists. what you're talking about is one more column to collate the personal achievement scores, not experience, of players for comparison, and a lot of various leader board ranks are already clickable columns with a search bar to see where specific things and players are in the lists.
we can see our own achievement scores in personal information, but yeah, there may be one in rankings, but i don't recall seeing one.
