I personally think it's a good raid, especially the first time you're trying with your Raid team to figure it out, and it has some surprises. It has the best lore of any of the raids in Destiny; has lots of lore on the Hive and Oryx and the connection to The Dark Below. Having said that, the issue people have, is that it is very reliant upon the whole team being in one spot to shoot the boss your trying to kill. It's stale on movement. Warpriest makes the team huddle together to shoot him while one player is killing ads. Golgorath, similar. Sisters are the same, every one get together to do DPS at the same time. The final Oryx fight is a bit better. But every raid has its plus and minuses. VoG was great at its puzzles and working as a moving team to defeat each stage, but really didn't fit the story or lore of the game. Bungie tried hard to fix that with later quests and story missions, and mildly succeeded. Crota's End was and still is the easiest raid to cheese. It's a piece of cake to solo these days. And it's mechanics are ultra simple. But in its prime, if you had beaten hard mode multiple times it was an accomplishment. Kings Fall was a great lore Raid, amazing scenery like VoG, but as I said above was very heavy on one location mechanics. Wrath of the Machine is not the longest raid, and the lore is odd in my opinion, but the team dynamics necessary to beat it are similar to VoG. You have to communicate and work as an active moving team to finish, and that is desired by a lot of players. So, all in all, four raids each a bit different flavor.
