Sorry If this has been answered or mentioned before.
I was just curious, why not have some sort of tracker that lets you know if you got the assist or killing blow on an enemy? The technology is seemingly there since it'll notify you if you've taken revenge or avenged a group mate. And I know there is/was an addon for pc that kept track of that for you. Now I'm not suggesting a menu option dedicated to stat tracking, but maybe a simple scrolling overlay on the side of the screen that says you assisted again [insert name here] or killing blow on [insert name here].
Thanks in advanced.
