Closing because this discussion is counterproductive. A factual correction regarding the OP: Kixeye is not making a regular policy of a new raid every 3 weeks; a good sign of that is the absence of a 7 day countdown timer in the game right now.
January's raid happened a week late: 5 weeks passed between December and January raids; then the February event put the raid back on the normal week (if January hadn't been delayed). The communication regarding that was not as good as it could have been. The mods have relayed player requests about the scheduling for future events.
