I wrote more stuff. Analysis: Role "mains"
Impact is a formula we developed that rates KDA and farm. Each role has its own formula. It is the mathematical version of “12 / 1 / 3 is a good KDA”. We have not adjusted it for 5v5 yet… but on the other hand, I am doubting whether it is that useful at all. Most of our visitors turned out to be experienced enough to not need a machine to help them interpret a KDA.
