I just like things very neat and tidy! And frankly so many of those forums are kind of dead.
That's why I suggest making the existing ones subforums. Nothing is lost, they still exist for people to make threads in, it just looks nicer on the front page.
These are great examples of what I mean:
You could for example make it look like this:
-Lotro General Discussion-
Lotro General Discussion and Feedback - Subforums of Player Suggestions and Store Feedback
New Player Questions
-Lotro Game Discussion-
Gameplay Discussion - Subforums of Adventuring, Epic Battles/Instances/etc, Legendary Items, War-steeds, Crafting and Housing)
Character Creation and Development - No Changes
Monster Play - No Changes
-Community and Social-
Community - Subforums of Kinships, PLayer Events, Guides and FAQs, Halls of Fame, Real Life Player Events, Off Topic
Creative Endeavors - Subforums of Roleplaying, Music System, UI, Cosmetics and Appearances
JRR Tolkien - No changes
Content Creators and Community Sites - No Changes
Real Life Player Events
I'd leave servers and support areas unchanged, personally, except to move Anor and Ithil to historical servers.
