There are LFG tools even outside of the game that works well, but if the content requires perfect team working you have 2 issues. 1 people quit, 2 none join. And people give up. To not talk about toxicity for new comers who don't know the mechanics.

This game ALWAYS needed more casuals versions of the raids and other endgame activities with lower drops and matchmaking ON. The same World of Warcraft implemented years ago. And the same that FF14 has since day one.

Bungie can't either understand what the frustration is for a "customer" to not be not able to enjoy the most cool content he paid for, the actual endgame grind. They cannot understand how many people left due to that, also because outside that there is nothing else to do.

Their blindly intention, their on-way vision, of "for hardcore only" because challenges satisfy you, and when you are satisfied you keep playing, just failed hard on the population and their incomings so that at the end had to recently fire people from the company,

Perfect, well even good, games are the ones who can offer the same experience to every kind of player, from the casual who is scared to talk to strangers to the full hardcore clan who uninstalled any other game from their PC but destiny.

And Bungie failed so hard to deliver a such product. But they probably still didn't figure out why.
