Addition of option to destroy rewards
Currently, players need to receive all the rewards at once; however, since it is inconvenient when there is a rare item that you already possess and you are unable to receive the rewards, we will be making it possible to get rid of the item without obtaining it. We are planning to implement this during this week’s test server update.
I think this is my favourite. "Hey guys, I just got my second Mekira Meikogai, and I destroyed it!"

Yeah that'll help frustration among those that STILL didn't get that ra/ex item they want.
