There is kind of an awkward moment at the end when people are too scared to leave in case nobody has voted yet (if that makes sense?) like people edge towards the exit. I always give one straight away, wait like 10 seconds, then just leave. I've gotten 5 so far, some from PvP and some from HM dungeons. I'm not expecting to get them a lot, I play DPS, and people probably aren't going to vote most of the time. I'm just gonna be happy when I do get one.
