Over the last couple of years, as so many folks have left the game and others have given up thinking SSG would ever focus on customer care, fewer people are using the forums. That includes and almost death of the server and kinship forums.
However, I glanced at this and will point to two I know of who have a variety of play styles but still organize end-game activities. The first is Tonic & Athelas and the second is Will Fight For Food. https://www.lotro.com/forums/showthr...ing-all-Levels
I couldn't find a recent post on the Kinship forum for WFFF, but ask in World for either.
I don't know where you are, but WFFF is European founded and has a lot of folks there and East Coast US. A&T is mainly East Coast with a few more people on at night for West Coasters. Both have a global presence, with the Antipodes represented.
