........................M/D System........................

It will work like this: 

Let's take an example:

The player 'Raaa' Raq' murdered 60 players and died 5 times, the M/D will be 12.00, the number of murder will be divided by the number of deaths, the higher your KD the more efficient you are.

The name of this Leaderboard will be Most Efficient Players (please if you think other name, talk in Comments).

This system will only work with players, (if the player don't have an account in Wilds.io, this system will not work), and will work only in Fort mode

Another example:

The player Dead Wolf murdered 6 players and died 12 times, then his M/D be 0.50
