I would prefer a separate match making/ private mode in an area the size of a small crucible map. They could be missions given to you from the different factions with different tiers of starting difficulty like the strikes, hell add in a nightfall one also. Example : Nightfall Defence Mission. Location: Moon Enemy: Hive Mission: Dead Orbit has detected a warsat that will hit the moon some time in the next 7 days. Guardian we need the Intel inside this warsat to help finish our fleet. Defend it from the Hive at all cost. Mission Objective: Survive 20 waves of enemy's and kill the enemy commander. Reward: 500 Dead Orbit reputation Reward: Unknown.
