I still have an account I log in once a month to pay my house bill and keep active and this new expansion might just make me play it somewhat full time again:
The Champions quest:
Become the next Lancelot, Cuchilainn or Balder as you undertake an epic quest for your King. Explore new zones, revisit altered lands, and bravely enter the revamped and more deadly dungeon of Darkness Falls to put a stop to the spread of darkness. By performing this service for their Realm, players achieve new levels of advancement, gain the ability to wield class-specific Champion Weapons, and acquire fantastic steeds to ride into battle.
Champion Levels:
Characters can continue to advance beyond level 50 with the addition of five new Champion Levels. Champion levels provide additional hit and power points, sub-classing options, access to special equipment, new Champion titles, and increased customization of mounts.
Sub Classing:
Champion level characters will be able to sub-class to gain additional abilities and learn new skills from other classes. For example, a fighter can learn a mage's spell by sub-classing. This will allow a player to add a previously restricted healing ability, damage spell or weapon style to their character.
Mounts:
Acquire a faithful mount to travel the Realms and charge into battle. Ride a warhorse, unicorn, nightmare, or undead phantom steed. Advanced mounts are available to Champions of level 45 and above, and can be customized with a unique name, barding, saddlebags, and armor.
