[2020] [Gameplay]İron Horse Raid Drop

Hi, I and my friends always enjoy this game. Purchasing every content. Love it. We complete every challenge every week. But İron Horse and Dark Hours never drop Ravenous or Eagle Bearer. I have four character. Every week in İron horse but 4-5 open box and drop nothing. 5 friend quit this game. Why? We play and 8 player did not drop Ravenous. Again and again. That's not a chance. Please get fix this.

Edit: Finally my friend drop Ravenous and bring me
