I've done the math --> The only late game league mechanic profit !

The league mechanic is just a delayed extension of your mapping loot, nothing else. Here's what you wanna do:

----------------------------
-DISABLE FARMING
-DISABLE SHIPPING
-DISABLE ORE
----------------------------
-DISENCHANT DUST
-CRAFT 8-MOD MAPS
-RUN FAILED CRAFTED MAPS
----------------------------
-MAKE SPECIAL FILTER FOR MAP RUNNERS
-LOOT MAP RUNNERS (KILL PIRATE BOSS)
-FLIP GOLD


Here's the long version:

WHY SHIPPING IS ABOUT 5% OF YOUR TOTAL FARMING:
You're shortest shipping is about 30 mins, you get 3 boats. If you go with frequency at best you'll be able to get about 3 divs/hour. Simply because your farming can't keep up with the amounts you need to be sending. 3 divs/hour is wasted gold. Same thing with ore, even if you speedrun your maps just for verisium it's still lower than the loot in your maps.
So shipping is out, so is farming, it's just wasting gold. Also setting up your ships and then looting them is also wasting precious time, maybe even upto 10 mins at a time. Plus there is diminishing returns on shipments, so you can't put in a weeks worth of mats and expect a mirror in return, it's not how it works.

MAP RUNNERS ARE ACTUALLY -> BULK SELLING FAILED MAPS:
The viable profit comes from your failed 8-mod map attempts. Your 8-mod fail attempts will never bulk sell, they usually turn out to be crap, but they can be bulk run. Run all 3 map devices all the time, setup a loot filter specifically for it, you will get more chances to kill pirate boss than with shipping. Map runners are more profitable than shipping.

FLIP GOLD:
The extra gold you can spend on flipping with Trade Website and Faustus. You buy stuff cheaper on trade site and then resell in Currency Exchange for more. It's more profitable to flip gold then anything you can do in Kalguur village, by far.

And no, sending like a super elite shipment of all you get in 1 week is no profitable, there is diminishing returns on your shipment.

IMHO I think Kalguur actually nerfed the overall looting. If map is splitting loot like 50/50, meaning instant item drops and drops converted to gold, then you're basically given a choice to RNG some of that loot trough various slot mechanics like Shipping/Map Runners. I like how they designed it tbh.

I get the feeling that only good loot gets converted into gold.

Rest is worthless.
