Here are some suggestions regarding the economy of the game.

1. Fix the agency, that would be awesome, and it would save everyone a lot of time

2. Improve the agency, and by improving it I mean make it possible to find every single item that isn't binded, via agency, including dshop items (also a time saver)

3. Remove the dil limit, but keep the npc that turns bulions into dil so that people can change their bullions back to dil (also make an option to turn all bulions to dil directly, instead of being able to turn just 1 bulion to dil at a time). This would be a very good change, because of: A. No more shouting like crazy if you want to sell anything that's worth over 1b, B. More information on the price of the items, and this last part would be a great help for new players getting them to know the value of items, and also not being "scammed". There are alot of people overpricing items that go for over 1b, due to the very fact that this dil limit exist, as there isn't a lot of information on the worth of this items, except for the mainstream ones like wed belt, gd or ulti weps etc, but usually items that are worth somewhere between 1b-10b are being overpriced most of the times(eg. 15x+9 items, 145~160 +9 weps, etc). So by removing dil limit + fixing and improving the agency ppl would get accustomed easier with the economy of the game , overpricing would go away(even if not entirely, those changes will definitely have a big impact against it), and trades would go much much faster.
