If this is the Statistic formula , Removing K/D/A would improve the quality of the the Games by so much. Ranks determined by K/D/A from D[high death/Low Assists and kills] to SS[High Kills/Assists-Low Deaths].
Note that Combination of Assists and Kills determine the Rank , not only kills.
This would put a spotlight on a Team Kill, therefore improving Team Play.
Ultimate Pointer would be the Win/Lose Ratio , this would/must be most important thing when player is Checked .
Im glad that you started this , i started similar topic years ago but it didnt get traction. Anyhow , im available for all the Testing,and Brainstorming involved to make this happen.
