I got to rank 5 got the gear and got the weapons then helped friends get to rank 4 and 5 and the only thing I got from the IB as far as a drop was the hammer late last night right before we quit. I wanted Timur's lash but oh well. I had a friend get Timur's lash the match after she hit rank 3. That is my luck though I have not really gotten any drops from the game at all and can't think of any exotic that I have that I didn't get from XUR and I have 2 28's and a 29 if I had shards they would be 29's and a 30.
