Match history assist heatmap idea

In the match history page there is a Kills/death marker per location it happened in the game.

I really like this feature, but think it can go further. When I am looking at the heat map for a good support, one who does not get kills, dies little, but assists a lot there is virtually nothing there.

There should be this for assists. To make it better it has ranging intensities depending on how many team members contributed to the fight.

Another thing is that death really look disappointing, and does not show how your death contributed. With some kind of assist thing, you can actually see if the call you made was #worth.
