The largest changes will occur with the three main instances of Angmar: Urugarth, Carn Dum and Barad Gularan. These instances will receive significant tweaks to the gameplay and new armor sets will either be added or greatly improved to add balance. In addition, many of the epic storyline quests will be reworked to add replayability. You can then access any of these replayable quests by talking to a Sage of Eriador who is located near the reflecting pools of the pertaining instances. Check out the complete notes from this dev diary, as well as a follow-up forum post with questions from players that are answered by the devs themselves.
