I don't agree with that at all Penga..
Whenever there's an update to a game there will always be at least one person telling the people who don't agree with it to be thankful we get anything at all... But If DW and other games don't add new things (That players enjoy), they will quickly lose their players and their source of income. And last years event for Christmas was great so of course people are going to compare this one to that and feel disappointed.
Truth is when you have an awesome holiday event if you can't beat or at least match the next years same event you're going to have a lot of unhappy players.
