I actually just experienced this EXACT same thing. I’ve been farming chests all day long and all over the map for the Hope Chest schematic. Well, when I got to weavers a couple of friends tagged along. One of those friends has no luck gear and no trophies…NOTHING. We did every one of the good chests and at the end I was like…hermm well I get a couple of schematics and one furniture item…The friend with zero luck got like 12 furniture items and about 9 schematics and a couple of recipes. This isn’t an exaggeration. I thought they were giving me stuff from a previous run, but they said, “No, this is just from the ONE loop we’ve done of Weavers.”
Currently I have
2 Minor Luck Trophies
Necklace: 2.5% + 0.5%
Ring: 2.6% (I’d use Weaver’s Knot, but I can’t help but feel it is bugged and isn’t actually the double luck perk)
Earring: 2.6%
Head: 2.4%
Chest: 2.7% + 0.5%
Gloves: 2.7% + 0.5%
Pants: 2.6% + 0.5%
Boots: 2.7% + 0.5%
Bags: 2.4% + 1.9%
In total that is 27.6% + 2 Minor Trophies (If I use Weaver’s Knot add on another 1.2%, which makes 28.8% + 2 Minor Trophies).
Here’s the thing, though. I will say that I got blown out of the water in Weaver’s and I was like…wow…I guess I’m wasting my time getting a luck set together. However, we then went to Ebonscale. My friend still got a lot of stuff, but even though I didn’t get a lot I could consistently see more purple drops for weapons/armor off mobs for sure and out of chests I felt like I was seeing quite an increase comparatively. I also started seeing a couple of furniture items I’ve never had drop. My friend also got a couple of items I’ve never had drop, but I did seem to be finding less, but MORE higher tier items. A couple of the furniture items were T4 and I had the book drop for upgrading my harvesting trophy, etc.
So, I feel like Thresholds are a thing. Perhaps once you hit a certain threshold you are much less likely to get the other stuff that is EASIER to get, but you can still get it. While it is still very rare to get the better stuff, you have a HIGHER chance to get those things and the people without a luck set have almost no chance of getting them unless they have that like ridiculous WoW mount luck of like 0.01% sort of thing.
Or…or luck could be bugged. I do think thresholds are a thing though. Went and upgraded a couple of my pieces and added Pristine pearls I definitely saw a loot quality difference. Perhaps for some reason Schematics might not be properly taken into account for loot tables, but I am getting much less of the Maple schematics and such even if I’m not getting much of the better stuff.
Hopefully that all made sense. Kinda crazy we both just went through the identical situations. Also…Weavers is kinda nutty for chest runs, definitely out of all zones it was the quickest and easiest to hit all chests.
Good luck on your hunt and hopefully we get some responses. I just never know if things are bugged or I’m unlucky with this game, and it’s so frustrating because if I knew it was bugged I’d focus on something else, but I have no way of knowing. =/
