There's a new article up on VGPlayers that gives a sneak peek at a new feature in the pipeline for Vanguard: Saga of Heroes: Rest Experience. The system being implemented seems very similar to one currently used in World of Warcraft.
Heroes may now rest in Vanguard! Resting increases the rate at which a hero will gain adventuring, crafting, or diplomacy experience. As the hero gains experience in a particular sphere, rest of that type is exhausted. Rest for each sphere is separate, and is designated by a blue bar on the character sheet of the corresponding sphere. For adventurers, rest is also displayed on the experience bar. Camping allows a hero to rest, occurring more rapidly at outposts. A hero may tell if he or she is at an outpost when a tower icon appears next to his or her class icon.
