There's a difference between cheesing and cheating. Mario's whistle was built in, forcing Crota to stay on his knees is glitching the game. This is why they delayed the hard raid, they'll have all this fixed by then and it will truly separate the men from the ladies. Also, from what I've been told, the glitch takes longer than legit. We only need to sword carries. People have solo'd this raid. Get good bitch.
