From my experience the drop rate of an exotic in the crucible is about 0.5%. I have almost 1600 games of crucible played. I have gotten 8 exotics from the crucible. Making the drop rate about 0.5%. In other words, one exotic in 200 games. [spoiler]Exotics i've gotten in the crucible: -Hawkmoon (my first exotic) -Ice Breaker x 2 -Patiencen and Time -Suros Regime -Monte Carlo -Dragon's Breath -4th Horseman[/spoiler]
