That's exactly why you would need a system that rewards the whole team for doing good and not reward each person. Worst case scenario, if you're personally rewarded for your DPS, it would be to your benefit to help other DPS die so that you'd have to take care of monsters more.

If the team as a whole is rewarded, you'll have no reason to backstab people.
