We'll be stopping when we feel comfortable with the new progression through the world. The overall goal is something like this:
Newbie: Levels 1 - 14 having distinct racial tracks to move through. While all races share at some point in the areas surrounding them they should feel more separate and equal now.
Early: Levels 14 - 22 having two distinct tracks through the Breeland experience, one following the epic storyline and the other following the storyline of Breeland. (Hush now about another area, we've heard you and know that you want another one. For the moment, Breeland has been restructured to provide those tracks.
Mid: Levels 22 - 32 having two distinct tracks through the Lone-lands, following Epic Book2 and the story of the Lone-lands, and the North Downs, stopping shy of Esteldin, Meluinen and Othrikar.
Advanced: Levels 32 - 42 having three tracks through the Trollshaws, Evendim (including Oatbarton) and Esteldin into the Ram Duath. This will also include epic Books 3 - 4.
High: Levels 42 -52 will have four tracks through the Misty Mountains, Forochel, Angmar and the southern Trollshaws into Eregion.
Some of these areas will need less work than others, but I cannot wait to get into the 32 - 42 stretch and finally make it clear for people where the questing is at these levels.
Once done with that push, deeds, class quests (primarily at 50) and some other low hanging fruit will get a new pass.
