It is less than 50k on my medium server. Why do you think it's higher on yours?
So since you have all that gold... how many tokens are you going to buy with money and sell for more gold?
How many tokens are you going to buy with gold to play for "free"?
Why do you think there is going to be more people buying with cash, thus creating a drop in price?
You do know that goldsellers still exist that are way underselling WoWs "exchange rate"?
The price has risen because less people are needing gold and not buying tokens to sell. People have plenty of gold so are willing to play higher prices f ortokens because it's meaningless against their millions. The thing that raises cost is how fast they sell... and they are selling fast.
WHen LEgion pre-patch and expansion hit... people will come back to game and simply buy a gold token at the log in screen. Way more than people will log in and buy tokens to sell. Wait and see.
