SE, it's gotten better, but you are still destroying the game for crafters!
With 6 characters each having 9 retainers at lvl 80 ilvl 480 (54 retainers) I have noticed a drastic reduction in the craftable stuff dropped on Quick Explorations, but it's still there, and it still destroys for the crafters. QE should give you what drops from dungeons, and sometimes raids, maybe some General-Purpose dye and other non-craftable stuff, but never, ever craftable stuff, that is the developers interfering with the local market economy.
