I have invested both in Duvencrune and Pilgrim’s Sanctum: Humility with two similar workers, but the output is incomparable 21  vs 7 per day?

I know, there's a little time difference, Pilgrim’s Sanctum: Humility takes longer, but even 21 vs 14 would be ok. Why investing 9CP for such ridiculous output? And these are the only two nodes that provide Trace of memory.

I have same issue I've been working on getting trace memory and they pretty much made it impossible I get maybe 5 a day from pilgrims sanctum humility and that's running 24/7 leaving my system on and other node sherekhan is no better then you have to go farm for hours to get weapon boxes which your competing againts everyone else in zone to only get maybe a few weapon boxes to melt down for maybe ten trace of memory then you have the next option to do alchemy quest to trade for 300 plus from info online but seems ya can't even get the quest to even do that option last time I checked market place had over six thousand plus on people wanting to purchase but none there so you wait and hope that you will randomly get some at a very high cost so a feel you defently pisses ya off.

And here I was thinking that it was the desert sun making my artisan human worker underperform...

@Dunespawn's "next option to do alchemy quest to trade for 300 plus from info online but seems ya can't even get the quest". They used to be a bit more common, but I went through 1.5 guru levels without getting any.
