Scenario 1-current market
Trader A:"My reservation price is 1000, but I'll see if the item will clear at 1500, and if it doesn't, I'll adjust it downward."
Trader B:"Hmm...someone selling at 1500...I'll undercut him by selling at 1400...LOL"
Trader A:"Ok...seems like there's competition...lets try 1300"
Trader B:"WTF! I'll meet you at 1200"
Trader A:"I'm going to sleep...gonna change to my reservation price...don't want to sell it at anything lower than 1000"
Trader B:*RAGE!!!* "WTF!!! THIS MARKET SYSTEM SUX!!! THEY SHOULD PENALIZE ADJUSTMENTS! THEY SHOULD NOT ALLOWED UNDERCUT!!! THEY NEED TO CHANGE THE MECHANICS OR THE GAME IS GOING TO DIE!!!"


Scenario 2 - price adjustment penalty implemented
Trader A:"Hmm..my reservation price is 1000, but since I can't adjust my price freely, I'll just sell at 1000 since I've bought it dirt cheap and still makes a good profit from it"
Trader B:*RAGE* "WTF???? WHY THE F ARE THESE IDIOTS SELLING AT SUCH RIDICULOUS LOW PRICE??? THIS SUX! THE MARKET IS BROKEN!! HE MUST BE A FARMER OR A BOTTER OR BOTH!!! THE MARKET NEEDS A MINIMUM PRICE MECHANISM SO THAT THESE IDIOT CANNOT SELL AT SUCH LOW PRICE!"
