There's a new LotRO launcher with several changes. A new region, Wildermore, has new quests, warbands, and endgame activities. The story is pushing players into Wildermore with Book 10: Snows of Wildermore. Mounted combat is getting a big update which will give players a class-specific trait tree for optimal maneuverability. The UI is getting worked over a bit to change the way players can view alerts. Players will now be able to pay for their housing further in advance, which will now go into foreclosure six months after they stop paying for upkeep.
