Had nothing but blue junk drop for me. The first round after reaching rank 5, Lash dropped for me. Finally. I agree though. The rewards program on IB is broken. Big time. They advertise it as being a ramped up crucible with greater rewards, but I don't really see it. Saw two exotics drop for dudes that finished fourth or below on the board (out of a hundred control rounds). That's about it.
