I am looking for good premade scenarios/levels for the War of the Ring. Does anyone know any good Arda maps with team slots pre-entered?

(I had found one earlier that was more a diplomacy map, but I can't find it again.)

Never mind, I found it again. https://www.warzone.com/MultiPlayer?TemplateID=1367855

I'm not sure about pre-set scenarios, but here's pretty much all the Arda maps on WZ:

Only the top 4 though are really worth playing; their quality is far and beyond the best.
