One game I used to play found that an item gave some people unfair advantage over others and devalued the premium currency, so they took the item away from everyone and refunded the premium currency amount that people spent to buy it. So if it cost 100 diamonds, everyone would see their mines go poof and get 100 diamonds apiece refund for them. Then everyone would have minimines going forward. Wouldn't take away the thousands of diamonds already generated by the old mines, but would bring back some balance to the game.
