PvP community in Destiny 2 has been disillusioned for a while now due to a lack of new content but Bungie will try to enrich the Crucible in the next few seasons.
Crucible has been lacking in Destiny 2 ever since Beyond Light arrived - maps were vaulted, Stasis came in and wrecked the place and the everlasting shotgun meta became extremely stale. The last two have already been addressed with the range nerfs for most shotguns and a series of nerfs to Stasis but there was no news about additional maps or game mode to refresh the experience, until August 4, 2021.
Joe Blackburn took to Twitter to walk fans through some of the upcoming changes before most of them get revealed in the next TWAB, on August 5, 2021.
Two maps will come back from the vault in Season 16 but Blackburn didn't reveal which ones will be included. The reason for the slow releases is apparently that each map has to be ported to the new engine that came with Beyond Light. After these two maps, we will get a brand new one in Season 17. Keep in mind that Season 16 is the start of the Witch Queen expansion so it looks like Bungie will not be adding them in the prolonged Season 15, which is starting on August 24, 2021.
Rift will be coming back from the original Destiny at some point during 2022. This game mode is somewhat similar to Capture the Flag you would normally see in competitive shooters but you are not stealing the objective from the enemy base - it spawns in the middle of the map and the first team to bring it back to the enemy's base wins points based on the proximity to their Rift. Other actions, such as kills, will also award points and the first team to reach 20,000 wins.
While it will be a welcome addition, Rift is not the only thing Bungie is working on behind the scenes and Crucible will probably become much more diverse in the coming year.
