if you wanna play SHK and farm/trade banquett etc i would suggest an older world..most parishes will be well developed and you can benefit from this.on the other hand if you want to play aggressive you can choose one of the older worlds too as there's usually wars going on. i think most people joining world 6 will be players that have played SHK for a long time..
i would join an older world to gain experience and then join in on world 6
