You are all a bunch of sad misguided meta-gamers who look at buildings only as a lootbox. For you TFP could as well just put rectangular cubes of differing sizes onto the map and call them POIs
If only the loot interests you you might as well just farm the smallest T5 once you are on the lookout for quality 6 items, before that tier3 probably offers some of the best value for your precious grind time. And naturally a missed sleeper is a major obstacle which decreases your farm efficiency to unacceptable values.
I hope there are still players around who can appreciate the design of Dishong as a building and as a dungeon. I only go into Dishong after a few (real-time) months have passed so I don't get into this state of seeing it only as a string of lootboxes. Dishong is for immersion, not for your industrial loot production.
