Wow, you really love to simplify things, don't you? Things are not that simple. You cannot simply drop any product into a market and expect it work work fine due to supply/demand. The market must be able to support the product. I cannot drop a $200,000 luxury car into a market where the average income is $500 a month... Supply and demand does absolutely NOTHING in that case. Even if there is a huge supply if the $200,000 cars, the price of the cars will never get down to $10,000 or something that market can pay for it. Never. The supply will be there, but no demand simply because the market cannot support it. Same with the CREDDs. The CREDD does not come out of thin air, it has a very real production value to it. It costs $20 dollars to produce. That's $20 of real, hard, cash. People that pay $20 for the CREDD, will expect a certain amount of gold for it. They are not just going to go "oh, look! there is so much supply, that the price of the CREDD is 10 gold that I can make in 2 hours... Sure, let's go ahead and sell it!!". That will not happen. CREDDs will have a minimum value that people will not sell them for less than that. People will not sell at a loss. This is where Carbine comes in. Ok, so we take that minimum value expected of the CREDD, let's call it X. If people can make that X with heavy farming in a month, then it's probably not that bad. However, if the gold making vs. the gold sinks in the game are wrong, and you cannot make X in a month, nor 2, but 3, then it will be a broken system. Same thing if you can make X in 1 week of playing, it will break the system as well. Supply vs. demand is not the magic solution you seen to think it is. It will try to balance the market, sure, but the market itself has to support the product, or it will fail from the start.
