Good stuff here. I don't like the idea of a stackable gp exchange. As it is now, the people that do have more than max cash, have their wealth in items. If this gp thing is released, all the people with high amounts of wealth will use this option over having stacks of items in their bank. So all those items they do have stashed away will be sold and most likely crash the market of certain items. Introduce more money sinks if this is really a problem. I also do not like how some of these options are catering to the duel arena. The duel arena is enough of a plague already. Why not focus this energy on making better content rather than giving people more reason to waste time at the arena? My experience and observation of the duel arena is just a bunch of people passing around the same money to each other.
