I wouldn't miss Crucible if it was removed, it's just not a part of the game I enjoy. Or interested in getting better at etc, I'm just not interested. Out of the people I know who play the game, maybe 1 out of 5 actually enjoy Crucible. And anyone else I know who does it, is just there for the participation pinnacle. Or working on a catalyst quest, that has an objective involving killing guardians with a specific weapon.
