As lifeskiller i dont want to earn as much money as a grinder, i know it would be not fair. However professions need some items to have a decent, fixed income apart from rng drop. Grinders will always have trash loot as base income, no matter the rng that day.
Gathering has got something...but fairy powder sells for abysmal price. Hunting you get ire horn and hides to craft into trading items...but not a good amount, at least low-medium mastery. Processing you get extra proc, not much. And so on, witch delicacy, catalyst, no money delivering them.
PA could do something without breaking the economy, lifeskillers must get some "trash loot" drop, not rng dependant, to determine money earned with every profession.
