For replayability: A few ideas: 1. Hard mode patrol. If this is selected, enemy squads are randomly spawned at lvl 40 or 41. The enemy squads have variety. Rng enemy spawns during patrol. Rather than same enemies spawning from same locations every time. 2. Small events where for one week certain zones are under attack by different enemy types (eg Vex on earth). Game story could update slightly based on how many enemies killed - like community events. If guardians win, enemy pushed back. If not, events get closer to the tower. 3. Occasional bosses at random. Like the public events.... But brutal and very rare. Eg Lvl 42 atheon in the skywatch. You know you want to. 4. Death match patrol- players in opposing factions are marked as enemies. Faction rep gained for every kill. Rewards at end of week for faction that holds certain zone(s) the longest. 5. New bounties?
