I never really put much stock into 'kills'. As a SMN I am doting everyone up, and there are times I am festering someone to death... but a lot of the time I am just ensuring that pressure is on everyone with Bane. There are also times I come upon two people fighting and help out my teammate by killing the opponent... and they worked so hard but they need a little help, so I help them finish off the person. It's really not fair that I would steal their kill just because I came and killed the person at the last moment. So, assists would be nice but really easy to get, as others have said. I would like if there was some sort of activity gauge to determine how effective people have been as a whole, BUT that would discount the people who spend the game guarding bases, who aren't going to see as much action as aggressors or people storming mid. At the same time, though, it would easily weed out the people who join and do absolutely nothing outside of follow the group.
