The amount of cheesing and the easiness of it after a couple runs has kinda made me think a little less of it. Try finding a group that'll do the raid without cheese! It's pretty tough! Plus, I thought Atheon was a lot trickier than Crota too. Once you get the timing down for everything he's pretty easy really....

Or perhaps they enjoyed it to the point of looking forward to other creations coming down the line.....
