The thing about this that worries me is the re-sellers. You have seen it done before, where there is only a few of an item coming into the market and someone is buying all of them and selling them at an inflated price, forcing you to buy from them. Hell, within reason I've done it, but I don't usually have the bank-roll to keep a monopoly. I've never been a jerk about it, and if someone sends me a /tell I always hook them up.
Now look at companies like IGE. They have the bank-roll and do not know the meaning of words like "Within Reason". There is nothing stopping them from inflating the market.
Example: Take the Glimmering Tooth. Used in the manastone heritage, gathered via T4 trapping. The average price is 30g right now, but if you look, there are a couple for 40g from the same person. They are obviously trying to monopolize the manastone quest part.
Now flash forward a year, when items like that will be going for RL $$, and IGE buys all of them for "X" amount and re-sells them for (Inflated) "Y". There bank roll is nearly limitless and can and probably will be employing people (or using bots) to constantly buy them the instant they hit the market for a lower price, thus forcing people to barter among themselves (personal interaction is not a bad thing, but ruins the broker system) or gather the resource themselves.
SOE will love re-sellers though. Think about all those "Small handling charges" that will happen. Twice on re-selling, once when the item is bought and another when the item is re-sold at a higher price. Isn't the fee based on a percentage? Yet another bonus for SOE.
With this news, I have seriously been questioning SOE and my relationship with them, and if these changes ever happen on my server, I will quit.
