I decided to go free from now seeing the madness of events you chain one after other. Each one requires more time that I usually spenf on work, family and friends all together, and it costs me huge amounts of money.
More and more people is doing the same and still you increase the gems needed for each event and reduce the sale offs. At this pace, the game will dissapear in a few months, so milk the cow as much as you can while possible.
