maybe it's to help make up for the lack of star crystals for soul leaves.... and lack of them in the item mall period!
Really something this essential to fortification should be available to all in-game without having to make gold to buy them.
As one of the more "senior" players in this game, i play for the stimulation, the comraderie, the sense of accomplishment. Gaming fills some space in my retirement hourse. Stimulation keeps the brain active.
Just my 2 cents.
