If Mistlands was like nothing done before then I'd wager it'll have more natural death traps. Like pits of lava in some fashion. Possibly something that keeps players from building wood structures of any kind. In MIstlands I built wooden structures at every point just cause it was too much hassle to build Stone Cutter multiple times to make a simple bridge our portal base. Made a cool lookout base within a Dvergr Tower once. That was kind of cool.
