What's most ignorant about match making? People that don't want it. If you have a fire team, then join up in orbit and there you go! You still have LFG in place. Match making in EVERYTHING would help a lot of people. More people would know how to do the raid without communication, or more people would be inclined to talk. It's the gateway for getting people to enjoy party chat. There's nothing to lose as long as people can still pick and choose their fire team in orbit. Think of zombies and the Easter egg. After being out a couple weeks, random people without mics do the steps on their own without someone keeping a walker for safety and things go smoothly. Duh.
