I like to play as support player in some maps, use the visor to tag all enemy so my team can be redirected quickly to target and cut off the cef ship when appear shot to sniper etc etc; why not introduce also for assist kills the support power maybe with double points ? like 6 for radar 10 for ion beam 12 for cef ?
Same as normal kill only if noone kill u.

support players shouldn't be getting dog tags for free

u only earn dog tags if you kill
