And maybe I'm missing something; or there is still non-surfaced info... But I wish optional objectives did more for a run, some ideas: In Skywatch, there's a secret room... At least on Hive day... you go there... kill 3 or 4 barrier champions, a bunch of adds... it unlocks an ammo room. How 'bout it increases your Prime drop rate by 50%? When you kill the HvT... How 'bout it has a 10% chance to drop a Prime when you kill it and increases your Prime drop rate by 10% from the final chest. If you kill all the Scouting Drones... 25% @Bungie for your consideration, please & thank you 😇👍💠.
