I propose that you could buy pack of 3 cheap identical fusion stones in Varanas (i mean with 3 random atributes, not for a low gold price).
When you are a noob and you find your first yellow stat item ramdonly dropped and you dont know what to do with it... usually you discard it or sell it becouse if you try to find 3 identical fusion stones... or in the worst case a combination that leave you a single slot fot the atributes it's too dificult (remember that you are not so rom skilled at lower levels below 30 or 20), i tried with add-ons and i never manager to do something interesting those old days.
So adding this to the sellers could help low level people to bost their gear for instances in a inexpensive way, something that almost nobody do at those levels, and some of them end saying that low level instances are imposibles.
Maybe the pack could have a slot for only one more atribute or two. Please think about it.
