I'm not suggesting throwing Morrigan Robes on sale, of course this would have to go under careful consideration under what would be available and for how much, but statistically a vast majority of FFXI's player base is very casual and doesn't have the time nor patience to deal with camping HNMs or spamming dynamis/salvage/nyzul etc.
Having the option of purchasing a small boost to get more out of the game without having to expend so much time and effort would do the game alot of good as a whole. But again this would have to be selectively limited and carefully planned to truly work.
