It was a week long event and the issue was identified and addressed on the 12th, a Friday, so Bungie had no way of applying any fix in time, hence they did the nice thing and offered one 320 ghost shell per account if you played CD. It wasn't because people "cried" that they kindly gave those who competed a ghost shell. It was because they couldn't fix the problem in time, and there obviously was a problem with the drop rates. If it had been a two week event or something permanent, they would have had time to apply a fix.
