Q. I have read that there are changes planned to improve the market system, but is there any more specific information available regarding these changes and the direction the market system will take?
A. We have continued to receive copious amounts of feedback regarding changes that players would like to see made to the market system. As a result, we are planning a number of revisions and additions to the system, the first of which are scheduled to be implemented in the next one to two weeks.
Specifically, market wards will be organized according to specific item types, making it easier to consolidate similar items in the same area. Further, if an item sold within a ward corresponds to that wards’ item type, the tax incurred will be reduced. Items not of that ward’s category may still be sold, but the tax imposed will remain the same as it has up until now.
We will be closely monitoring the trends and developments of the market system following the implementation of these revisions and new features, and will continue to make further adjustments and alterations to improve player usability and convenience. For example, we are currently looking into options that will provide players with precise information as to which items are located in which market areas, or the ability to seek out specific items without the need for speaking to retainers, and more.
Also, we are now taking steps to increase the number of retainers that a character is able to simultaneously employ.
