This is a long, exhausting quest, and in some time during efu:r, it had it's rewards considerably nerfed due to it providing 500gp per person or something insane like that.
I recommend:
1. It get something similar to 'boxes of the city' with a supply satchel for each person. Kinda like Morghoul Goblins and Gnashrim Orc Quest in the Mongrelwood.
Or,
2. The gold reward at the end of the quest is restored to its original levels given it's a 'random' quest and cannot be reliably 'farmed.'
