Have been done a lot of discussion on lots of group pages.
Unfortunately you shut down discussion on your own facebook page.
Besides you have never commented on any suggestion on your facebook page.
Many players are dropping out as you dont offer any events. If you look around most games are offering events for any type of celebration. The main reason is that when there is a public holiday people tend to spend more money. In the meantime, while you are not offering any events, "spenders" will invest in other games for events and eventually will quit this game.
Not offering an Easter event, is like stating that you have quit of developing of the game, completely.
Eventually, what I am saying is just a theory. YOU can check your bank statements and evaluate the benefits of events
