There's no point wiping the servers, until you have sorted out the Duping/DDos roll backs!! I really enjoy this game (and have done for 2 years now, and also knowing its pre-access so can accept the issues) but unless this is sorted then the full release game need's to come with a consumer warning, that warns gamer's that maybe interested in playing on official/community servers will not be an even playing field!! The excitement of PVP/tribal wars through the fair means of big tribes and hard work is not how these servers work. Instead the ability to be able to force a rollback and Dupe your attacking Dinosaurs just because a tribe successfully defended themselves, and thus playing by dishonest means.
As I said, I accept its pre-release, and that this issues do exist and are part and parcel of the game as is... But by not warning a potential buyer that will pay is excess of £45/$60 for a full release version that this is inherent in the game you really are going from Decent game making Devs to money grabbing moguls!!
