It is a fairly terrible system. Two pieces of tank loot drop early and we both sigh because we know any further tank drops will rot from being locked. Stupid, stupid design. Change it to per boss per week lock, problem solved. With the new myth cap you are pretty much gaurunteed one i90 per week, so why is the i80 gear more random and restrictive?

No one should be shocked that people drop because it is a failed system. In fact, more people should drop to force SE to review it.
