I know the feeling. I bought my Dragoon headpiece only to have it drop in A11S two weeks in a row. ;-;

Unfortunately, they do it this way to keep people running content. If we could get a full refund on Scriptures, then I'll have no reason to run Expert for a week or I'll BiS my main faster, thus only need to keep running Savage if I level another job or have an alt. They want to keep us subbed for as long as possible. Frustrating as it can be, the tomestone grind does that.
