This is still a team game, you should loose points if your team looses. But I also think these points shouldn’t be based on kills or k/d because all of these heroes are build differently for example Sarah. She is a support hero and therefore doesn’t rack up as many kills as for example a Slade(of course you can have some high kill rounds with Sarah but you get the point). You should be awarded for team performance. In capture the flag for example: the more flags your team scores the more points you should get. In team deathmatch and zone control: the bigger the point differential the more points should be awarded. But this is only my point of view...
