Drakkar - worst addition ever!
You have about killed this game by introducing the Drakkar item. Please get rid of it and save logic to the gameplay we love so much. Everybody makes misstakes, Drakkar item is your largest.
Kingdoms where people were making their homes are being overrun by accounts larger than an average clan size. Players leave the game in numbers as a result. I am sure by now this must be obvious to you. If nothing is done I personally give this another few months. After that you can safely rename Vikings .. into Edick Renegades.
