I turned valor 60 about a week before the patch that changed the bag drops to tokens. I had 2 pieces (wrists and belt) of BM gear when the patch hit. It took me about 3 weeks to complete my BM set doing all my dailies and weeklies. At first I had maybe a 10% drop rate but in my 3rd week nearly every bag had a comm. Overall, I would say I had atleast a 40-50% drop rate. Since completing my BM set I have been able to nearly complete a 2nd set for healing. With that being said, I have only gotten 1 comm this week. If you take away my 1 week hot streak, then I would have been in the same boat as many others.
