I had an idea, like people create parties or teams. Then team/parties can enemy other teams and on their name tags it would appear red. It would help track enemies down easier. Or if not this, we can add like a person targeting a specific person and once again their tags would become red. Just a idea on how to make targeting easier.
This would increase Teams Ganking on players more often due to the fact they can't hurt team mates now. No support.
