The trading post is something unique yet looking like an outdated version of the Grand Exchange. My opinion is that the GE would suit the originality of the server better.
The main reason I am basically posting this thread is that we need to focus on whats going on in trading post currently.
There are heaps of high tier/skilling items and whatnot with inaccurate prices which are currently sleeping in the post for thousands of hours without them being touched/sold. This is definitely unnecessary. We need a trading post cleanser like this; Items which dont sell for a period of 168 hours (1 full week) should be returned to players bank accounts, or the offer being put in abort status if their banks are full. This would accurately freshen up the prices of items every now and then.
Another problem I find with trading post is that players are constantly undercutting one another every couple of minutes just to get rid of their items. A system like grand exchange where items sit at certain prices of which they are actually been actively traded for, either a few % lower or higher of the street value depending on demand and supply. The street value should be changing every 24 hours either going up or down by a small percentage finding its balance of inbetween sell and buy offers. Not sure if its possible or easy to add this system, its probably an automated log system where it tracks all sales. Would be nice for the stability in prices of most items.
