Love the idea. But that would mean they would need to invest development time/effort/money into creating a new game mode. A new game mode that only comes around once a year, and only during a few weeks. During a free event. Which means they won’t be able to cash in on it. (While simultaneously nearly all other parts of the game are barely held together by thoughts and prayers at this point). Not to mention the preceding miles-long list of QoL updates and bug fixes people have been requesting for years I’m afraid you’re stuck with a “Bah, humbug” from Bungie on this one.
