提案/Suggestion
Make a page for trading zenny for gathering and Refinement materials, having it refresh weekly so the quantity is limited. It can be so leveling Hunter Rank would directly effect the quantity of items you may purchase, this will engage players to play more and try a variety of set builds.
現状/Current Status
Zenny is often overlooked by those who play regularly and find little need for it, while options are limited mostly to the daily quests that give needed materials. New players also find it hard to get into a game where there is so many things to try but are limited by the same pitfalls.
