ArenaNet details their scaling level system mechanic for Guild Wars 2

Gamer Limit writes: "At a recent press event, ArenaNet has informed Gamer Limit that considerable effort will be made to ensure that people of all levels could enjoy Guild Wars 2‘s content in the final build of the upcoming MMO. For instance, if a level 80 player were to revist the very first starting area in the game, Guild Wars 2 would scale down that player’s statistics so that they didn’t automatically one-shot all of the locale’s enemies."
