What I think most ppl not getting is that pick up groups for raids have a massive of chance to fail on raids. Bungie is doing you a favour not letting you get stressed.
You can only get loot from this content once a week, how mad will you be once your party disbanded because everyone decided not to play as a team? or you are the only one with a mic and trying to organise everything.
Bungie will get much more heat from ppl complaining "the content is too hard you need to scale it down" or "you need to make everyone that join my party have experience, and a mic"; then from this decision.
Also with the insertion points its much easier for casual players to organise to continue a raid on another day, instead of trying to smash the content in a long gaming session. With a matchmaking group, you wont be able to do that.
Above all that: how hard is to make 5 friends on PSN/Xboxlive and get a group going? You will probably meet some good players when playing strikes. Just add them to your friend list and give a go on the raids.
