Hi! there are just my personal thoughts on the topic

I'm just thinking that "auction" feature might become "move-point" of the whole server
It just sounds like whole server might move towards economic metropolice the moment "global" auction appears, because auction thing is pretty useful for making money and trading staff (wow, obviously

).
And at that point whole server might just think "hm, i can make my life much easier with auction, or keep sticking with other node"
That might result in situation, when "mass" will be on side of first economic metropolice
Just my personal thoughts thou
