The whole raid thing is maddening to me. The vault of glass, and I assume the new one based off impressions and the first room which I played, is one of the greatest online FPS experiences I have ever had. The design of that raid is so unique and interesting, the complete opposite of the rest of the game. So why in the hell is the best part of the game locked away from a huge chunk of the users.
There are a ton of people that don't have enough friends or time to coordinate a raid. Many have no clue about those matchmaking sites, why would they, it's the games job to provide the content. A bunch of destiny owners will never play the raid which is a huge shame.
The raid should be the entire game. I can see the amazing level design, it's proof right there that Bungie can make amazing gameplay content and yet 90% of the game is basic almost horde mode like stuff. Imagine if Zelda was mostly an open world fetch quest game, the worst kind of MMO garbage and then there was one Zelda dungeon at the end. Wouldn't you be confused as to why the whole game wasn't built around the dungeons?
The raid mechanics and that style of mission could be done in normal story missions. It could even be done in single player. Raid gameplay doesn't need to be 2 hour long gauntlets with a perfect 6 team squad. There is so much they could do with that kind of game structure, having very specific unique goals, puzzles to solve, new gameplay mechanics to discover, bosses which require unique strategies. That's should be the game!
