I haven't done Prison of Elders often. I actually had a stockpile of Keys until I turned them in for rep this week. Last night I did the level 41 POE matchmade. After getting through the last round, I made sure I didn't rush down the hole to the treasure room, knowing I could die if I wasn't careful. Right before I reached the bottom the match ended, and I was whisked to orbit... shut out of the treasure room. Don't be a jerk. Let everyone who worked for the rewards get them.
