That's the nature of the beast right now, and you yourself point out 5/8 aren't gonna get anything even with your proposed solution. Under the old system, your loot just would never drop--that "20 weeks" figure (ignoring that most don't field a full set of Savage accessories) more or less happened to my group in Sigmascape. Our nin and bed didn't get a single Aiming drop from the first floor for the whole tier, had to buy all of their accessories from the vendor.

This is the best loot system XIV has had for a while, probably ever, for Savage.
