At this point its only for glamour items anyway. And I think they are still available from hunt seals if your luck is just that bad, which is faster anyway. Most the time in dungeons myself and maybe 1 other person rolls on them, so its not like they are a hot commodity. And most ppl I know just get the piece of gear and trade it into the gc for seals. So they have to take that into consideration as well when determining drop rates on things such as this.

Its not like they are making actual needed gear that much harder to come by.
