You are right, I don't see a good ...or a even a normal free event in a lot of month...looks like they need a lot of money rigth now hahaha.
But a good idea could be --- Add a pay event....but also add a XP event, or Drop event(like the peaches). But do something to move a little bit the game....
rigth now we are only wallets walking in the game.
@Juji @Hime - I hope some one you read this topic...and try to make something .....or talk with the devs....and btw I hope we can see again the preview event list as time ago.
