General DiscussionTotal Kills / Total Deaths / Total Assists

Maths :)

There is, its called "hard work".

Overall KDA 2.24

Overall Kill Average 5.25
Overal Death Average 8.1
Overall Assist Average 10.8

....and this is why global KDA doesn't mix well as the heroes are so unique that it just messes everything up.

Heroes > Filter: Game Impact > Select table data > Paste as target formatting into excel, notepad > Do the Maths.

Yeah, if you really want to do it just add up the numbers from all your heroes.

But its just not meaningful. Getting 2 KDA on omniknight (if you play him properly as support) is really very good. But getting 2 KDA on Anti-Mage would be terrible.

Averaging those numbers doesn't make any sense.

you must have perfect micro skills
