Through the interview between the Executive Producer Jeffrey Steefel and mmorpg.com. From the answer from Jeff, he gave us a general review and explaination on the new features of the new expansion, he promised that it going to be an RPG experience for players in terms of being a 3D environment that they have never seen before. We can see this would be very exciting.

"10 new levels, a whole bunch of new content, tiers of crafting, new tiers of mastery for crafting, the ability to specialize in a particular type of thing and join a crafting guild, whole new avenues of exploration for collecting Traits and Trait Sets, but most of all, it's the legendary items system"

Steefel went on to explain that part of the appeal is that players are going to be able to interact with their items (primarily weapons and class items right now, with more to come down the line) in a whole new way.

"This is a form of elder play mechanic," Steefel said, "that is unlike anything that has been available in this kind of game before. It has some similarities, but it's really in total something that is much deeper and much more robust than what players have had to do before. The idea that you can create these weapons or items that essentially become a member of your party, that travel with you through the world that advance in level with you through the world. During the entire advancement process of the items, you are customizing the direction that you want them to go."

He said that the system is great for players who are sick of simply "outgrowing" their items and having to junk them in favour of something new. This feature should provide players with a bit of a sense of ownership as they create and craft the exact weapon that they want to use. Through all of this, Turbine hopes to open up new avenues of what they call elder game play. The Legendary Item system becomes available to all players at level 50 and not only allows them to build their own, special weapon, but also provides them with another goal for the endgame.

And Two new classes that will be available for players who purchase the expansion regardless of their level: The Warden and the Rune-Keeper will both be making their first appearance in this expansion.

The expansion rollout will see a new area, Eregion, made available to players (with the exception of the actual path to the mines which is a part of the expansion).
The new region will see new general content and new instanced content.
The new trait set system: Each class has three different trait sets to collect. Players can collect up to eight traits. Each time you get a new trait, you get a slightly higher bonus. All eight traits will open up a Legendary trait.  The Epic Story will be concluded with Book 15.

More detailed information will coming soon. You can have a discussion in our forum.
