Thanks for replying, Polog. It's good to know that someone is reading these posts.
One thing that I learned in my business courses is that if you raise prices, the customer needs to feel that they're getting something more. Otherwise, they feel cheated and that's how I feel. If balance is the goal, then the prices should have been adjusted at the same time as the price hike on diamonds.
The only reason I'm posting anything is because I enjoy this game and want to continue playing. I don't have time to be truly free to play, so I need diamonds in order to progress in the game. Unless prices are reduced in the shop or there is a diamond sale that is comparable to the 140% ones, I can no longer purchase diamonds and will begin looking for a more affordable pasttime.
