This is what this game is missing... Adding a feature where you can melee another guardian and if they accept, initiate a duel to the death. Allow wagering on outcome with glimmer. Maybe add rewards with Rep for vanguard or factions. Give a 3 second countdown, and lockout weapon swaps, supers, and grenades. Primary weapons only. And enable level advantages and caps to prevent duels +/- 3 levels from your guardian. Only available during patrol/missions when you're in common areas. Would add some more playability to patrol other than the boring bounties we've all played over and over...
