What you are listing is not the original KR settings of 7.8, it's a custom change for another region as far as I know. Our Gold sand Shop is the KR 7.8 Gold sand shop (with our custom change for the reagents Costumes and combat Exp Extractors).
So what exactly did you hold off to demand a custom change with more useful items for the Gold Sand Shop like robi1102 listed above when there is already the possibility of custom changes?
It's a choice. The choice that was made is to have what we have now.
