With the many style motifs that are now available, and the cost of making full gold sets of CP160 armor and weapons, I would love to see some type of morphing system that would allow us to be able to swap one current style into another (with some type of cost of course, just not the price of a full gold set).
I can see that this may not work for those people who aren't crafters and are unable to alter their own gear, but I'm sure some kind of solution could be discovered.
