You can meet new people playing the rest of the game. You don't need raid matchmaking for that. That you wouldn't abandon your group says little about everyone else. Especially when we can look at MMOs with matchmaking and see how players behave. People tend towards self-interest. Options that benefit the individual at the expense of the group hurts the community; removing such options benefits the community. Full stop. This kind of behavior can't just be educated out of the community. No more so than telling people to obey the law fixes all crime: we still need police to discourage criminals, and we still need game design to discourage assholes. That's an essential ingredient for a good community.

You're right that telling people to obey laws doesn't fix all crime, but it does for a lot if people. As I have said there will always be a subset of players doing that. That was evidenced in the strikes that I played. Penalising everyone due to the actions if a group of people isn't fair. Removing options for people to matchmake for raids is exactly that. The full game isn't out yet and we don't have first hand experience of how the destiny community will behave. If people do have a bad experience with the matchmaking they will always have the option of organising with 5 other people forming a fireteam and doing the raid together, be it friends from work, school or in a clan. Nothing I'm suggesting says that you can't do it your way. I'm suggesting leaving options open for everyone regardless of their style of play. Also keep in mind this isn't WoW or any other MMORPG, the game style is different and will attract a different type of player (and some MMORPG players as well) I know that I may struggle finding groups to raid with due to time zones and lack of friends with ps4. So matchmaking if it's there would be beneficial to me. If the experience is crap like you are suggesting then I'll work harder to find people but I wouldn't object to the option. Educating the community is how we make changes ourselves, otherwise we become bitter, jaded and elitist. It was only in the last few days if the beta that I felt confident to jump into the crucible (and my stats show that confidence was unfounded) how will some one new to the FPS and/or MMO genre build eh confidence to attempt the raids? On another point bungie have made an effort to stay away from some MMORPG elements, the no trading element encourages people to work for their gear, and if you bail out of every raid then you will never earn the cool kit. The game as I see it reward the grind not quick immediate pay offs. We have yet to see how this effects the way the community plays. Edit: Also I do believe my first suggestions were game design ideas to punish assholes... This might minimise the impact you predict, more than anything I've suggested so far.
