I had a F2P account to start with, but I just purchased the Rise of Isengard Legendary Edition. From. The LOTRO store and got elevated to a premium account. From what I have read, I understand that I now have access to all the quests and deeds in Ered Luin, the Shire, Bree-Land and the Lonelands (premium account) as well as to all the quests and deeds in Dunland, Gap of Rohan, Nan Curunir, Trollshaws, Eregion, Moria, Lothlorien and Mirkwood. I now also have access to the Isengard Expansion.
What I would like to know is what expansions or quest packs am I missing and should purchase now.
