I don't want to be forced to play with people. Often matchmade players impede progress and keep you from finishing bounties, quests, etc. Please give the option to disable matchmaking.
I assume you are talking about strikes as I can’t think of another matchmaking activity that would cause you grief when completing bounties and quests. If so, I always use the legacy nightfall playlist if I want to focus on completing certain items solo. For nightfalls and nightmares, just bump up the difficulty to no matchmaking.
