KD ratio makes a relation between how often the player dies compared to how many enemies they kill. A good KD ratio average is around 2:00 implying that the player has taken down twice as many enemies as they have been killed. Most casual players have and maintain a KD of around 1:00.
In Call of Duty (COD) games, a Kill/Death (K/D) ratio of 1.5 is considered to be above average. It indicates that for every death, the player achieves 1.5 kills. However, what is considered "good" can vary depending on individual skill levels and the specific game mode being played.
