Completely agree with matchmaking - as someone who works and has family commitments I cannot simply commit to playing the game on a regular schedule with a pre-made strike team, matchmaking as an absolute lifesaver for me who logs on only about once a week (although I am still level 32 and complete the weekly heroic pretty easily most weeks). It is so annoying essentially being locked out of half the post-level 20 game because my circumstances stop me being able to join a strike team. Maybe it will be impossible for a group of 6 randoms to complete the Vault of Glass, but shouldn't we at least be allowed to try?
