The rng for this is set far too low; I believe the people who quoted 3000:1. To put this in perspective, that's the same odds as getting struck by lightning. Or if you prefer poker parlance: 4 of a kind is at 4100:1. When your only play is 4 of a kind or bust, the game isn't worth playing. It's truly not worth the effort, and therefore not a good or fun event - but I know people will anyway. Disappointing design decision, but oh well.
