Currently leaderboards in Playfab are based on the score of the player. We'd like to have a leaderboard where players’ positions on the leaderboard are swapped based on the outcome of matches.
This type of leaderborad is common in RPG f2p games - one example is Star Wars: Galaxy of Heroes and its fleet arena leaderboard, I've attached a picture to this post.
At the moment the main problem with implementing it on Playfab is the atomicity of the swapping operation and only viable solution is to implement it externally, i.e. on a custom server.
