https://getsatisfaction.com/goko/topics/allow_replaying_a_game_against_botsIt sounds like goko is about to implement the new deck builder in the worst way possible, so that it will be almost as unused as the last, laden with heavy menu usage, requiring you to save kingdoms then set them up to play them (might just be the way I'm reading it, but with their track record for user friendly UI, I think I'm reading their responses correctly).
I urge any who care about the details of this feature to sound off ASAP, I know they said they were looking to release the changes soon. I'm sure some people might like the way the new one sounds, I urge them to make their voices heard too, as I'm sure my opinion on the matter isn't the only one.
