Crucible has more options like Destiny 1, so bring back fireteam rumble. Doesn't even need up to 3 players, just one additional player is enough It was fun having self imposed challenges then go to Rumble matchmaking to fight players of varying skill levels with varying loadouts, from niche players to meta players. >Inb4 but people would team up That rarely happened, and since Destiny 2 is on console, Bungie coudl set up a system where you record a game, sent it to Bungie, and they suspend/time out players from Rumble or the Crucible if they team up.
Play in custom matches instead? There is cheesing that would happen if you let people bring their friends in with them.
