Ive beaten crota several times easily and you're right, thw Crota raid isn't hard at all. The deathsinger is the more difficult part but its not as hard as people make it out to be. I will admit to cheesing because it's a part of the game right now BUT when they patch it I'll still be able to beat the raid. I cheese because I can. Atheon raid is so much better because it still has a level pf difficulty thats makes it hard. Beating Crota legit only takes 40-45 minutes.
