I'm glad to see a new post in this thread as I've been wondering about this more and more as MoM nears release. I'm really hopeful that something will happen there. I'm absolutely convinced that a huge reason as to why WoW has held on to such a large fanbase is due to game add-ons. I would really love to see something happen in LotRO since I play it most.
Honestly, at this stage I'd even be happy with some sort of LotRO take on WoW's Armory
. I really liked the addition of character signatures... I feel like in some ways the game just lacks things that make people feel more connected to it as there's so little to share with others.
