Not really, RNG means a small percentage will have apparent bad luck, and only those people complain, so it looks worse than it really is. I would suggest two things: 1. A weekly iron bounty for a key for those who don't have time to play 30 strikes a week. 2. Increasing drop chance the longer you are in the strike queue. Not a huge increase, but enough to get you a 25% chance after 4-5 strikes and 90% after 10.
