Why didn't the Valar do anything to help good on Middle-Earth? Were they still annoyed at Feanor for that hopeless war on Morgoth? If even one of the Valar were to travel to Middle-Earth Sauron would be basically blasted into oblivion
.
Maybe they couldn't do anything to help anymore because of the removal of Valinor from Arda, or maybe they were just lazy
!
