The most intuitive calculation is based on k (kellkill) d (die death) a (assist assist), but not all heroes are like this. Different occupations will be based on different algorithms, and KDA is just one of the data.

For example, the shooter's killing and output are high, the mortality rate is low, and the multi-push tower scores high, so the weight of injury tolerance and control is relatively low.

Assassins give priority to kill rate and participation rate, so the weight of average output per game is not high.

Tanks are mainly based on participation rate, injury tolerance and control, so the weight of killing and mortality is not high.

According to the attributes of heroes, there will be some differences. Cai Wenji and Bian Que pay more attention to the milk quantity of the whole team, while cows and demons are more inclined to bear injuries and control time. Therefore, every profession and hero actually has an independent algorithm, which can not be calculated by a set of propaganda.
