The new year brought Book 12: The Ashen Wastes on February 13, 2008. This was the first major update that didn't include the introduction of a new region. What it did bring to the table is a mix of revamps and new features.
The high level adventuring area Angmar received a major overhaul, making it significantly more solo friendly. many elite mobs were taken out of the solo area population. And the boars, oh the boars, were mostly removed in favor of more menacing mobs. Finally, the questlines were smoothed out to move players along to area more appropriate to their leve.
PvMP players received a new PvE dungeon, the Delving of Frór. The Creeps and Freeps battle for control of the dungeon and should one gain access while the other was battling a raid target within, well, that's when the real fun begins. New armor and items were also made available to the player side.
Cosmetic enhancements were introduced to the game in Book 12 as well. The outfit system allowed players to choose one set of armor for stats and another for display. The barber system allowed players to change their hairstyle and facial choices, even adding a few new hairstyles to the game.
Finally, three classes got a revamp this time. Guardians received a mix bag as their defenses were both nerfed and buffed, they received a dps stance and gained some utility. Burglars got a buff to nearly all their functions including damage, debuffing, trickery and crowd control. Champions also got an extra pass that gave them a stance that was part offensive and part defensive. This round concluded the class revamps planned by Turbine.
