No I don't understand it, it's stupid to want to play a game that is designed and billed as a multiplayer experience to demand to play by yourself. Sure there are times when you will be alone in this game but that's not what it's built to be primarily played as. If you are a recluse and fear talking to people or get anxiety in social situations this isn't the game for you. There is any number of other games to play that feature full on single player content. Furthermore no, adding matchmaking to experiences like raids will just lead to their dumbing down and simplification. All matchmaking in raids and dungeons will encourage is AFK players, people ill equipped for the raid, underlevelled, no mic, no idea what they are doing. It will be a complete nightmare. Hell half the idiots can't even grasp the simple concept in vanguard strikes to MATCH ELEMENTAL SUBCLASSES to get credit for your 3 strikes a week for a powerful drop. If half the people can't even figure that out do you really think a more complex and engaging encounter like a raid will be anything but a total shit show?
