You're not all unlucky at the same time. Few people visit the forums, and people who feel it's fine aren't going to be posting.
TO economy doesn't show anything either. Servers age, more and more high level players work up gold chains, so coins are decreasing in value (the towers for christmas didn't help). The aging population also has a higher and higher need for granite to upgrade, so supply and demand kicks in and bumps the price. Nothing special.
