The source of this issue is the fact that most of the player population is concentrated at the higher level range due to how long the game has been out, and that newer players are unable to find groups to tackle the epic storyline content, resulting in them having to skip what Turbine considers a focal point of their game.
So what's Turbine's proposed solution? The introduction of an "Inspired by Greatness" mode. The new mode would enable players to dig deep down inside themselves and find inspiration to accomplish great things. In game terms, players who select this mode will be given a significant boost to morale and power, in and out of combat morale and power regeneration, damage, and healing.
"Inspired Greatness" will be available for all books starting from Volume 1 Book 2 with the release of Siege of Mirkwood on December 1st, 2009.
