Bungie is really bad at the details of their decisions. This actually wouldn't be bad if there were checkpoints on each access level. Right now, only the dedicated are doing it because every wrong code equates to restarting the whole thing. No one has time to do this except those who do it for their jobs. With checkpoints, all fireteams in the community could be on the same spot and then it's just figuring out the puzzle for that spot. No "attrition" battle, which is completely and utterly stupid. One simple choice and it could have alleviated a TON of the backlash.
