This is undeniably true. But the issue isn't what is, it's what we want. We want the raids to aspire to the complexity of the raids in traditional MMORPGs. Vault of Glass is almost universally regarded as better than Crota's End in no small part because Crota's End is simplistic in comparison. And we might hope that Bungie is listening to that feedback, because in a recent interview with Kotaku they hinted that the Taken King raid will focus more on coordination and puzzle-solving than either of the previous raids. For my part, I just can't reconcile that with a system that throws together groups of players by randomly drawing from anyone with their hand up.
