Lord of the Rings Online: Mines of Moria than just the Rune-keeper and the Warden. Chances are, if you already have a favorite class that you've leveled to 50, you're going to be more interested in getting that character through the mines and onto 60. Turbine realizes this, and have recently written three wonderful new Developer Diaries featuring the Burglar, the Hunter and Lore-master's roles from 50 to 60.
These new Dev Diaries do more than just list new skills, they actually cover certain roles that these classes may play to use certain spells more effectively. Plus, with the introduction of trait sets (much like armor sets work now, with bonuses given to certain trait combos), the roles are much more defined for each class. Check out each of these three articles for the Burglar, Hunter and Lore-master to get yourself ready for Mines of Moria, coming very soon!
