You sir are an idiot. It's called RNG. I ran through las week on one of my characters and got nothing at any encounter the entire raid. Wait, I got two shards at Oryx. So basically I lost 18 shards for doing the raid. Its part of the grind. If we got a drop every single time there would be nothing to grind for after a few weeks. Its fine how it is. Makes getting a good drop feel even better.
