Though I have always liked the Lone Lands, these improvements do sound good. A solo version of the Weathertop instance is very much needed.

Turbine needs to go further, however.

They should offer solo versions for ALL of the Book quests, imo, and revamp their travel system to make the business of getting around in that game less tedious. My suggestion would be to grant all classes (not just hunters) the ability to port (only themselves) to the major cities, but allow just hunters to port (themselves and party members) to cities AND camps.

Those two issues (travel and group epic quests) -- and my general frustration with finding groups for any of the instances -- are the primary reasons I eventually left this game.
