I could see your point, if the raid ended up being something that was terrible or buggy. With a few determined players and backfilling a mm group will become an organised group organically and completely within the game. I don't know seven other people who play this game and getting people to cooperate and function in Destiny with 6 was a pain enough. The gap between pc and console will always be there. And just like this raid at the beggining it seemed imppossible to do with randoms, but now that everyone can do behemoth with their eyes closed the matchmaking is really appreciated since high-tier players can do the harder coop content as easy as pressing a button. If you are up front that you want to learn the raid and find people who are with you or are willing to help your experience will be pretty enjoyabl.
I am essentially locked out of content I already paid for.
Look at the positives and negatives, not just the positives. They can try MM if they want and probably waste their time if they get a couple people who are clueless. It's one thing for a 10man WoW raid for RF difficulty and watered down content to have a few stragglers. The funny thing is that for the people that do get it first, it'll pretty much only mean anything to them, as the majority of people will probably not even care to look at the plaque, since it is insignificant. Horses for courses, some folks just treat like a casual game! It's not dumb in Destiny 2. They just want to play and get the loot.
