9/10
Great idea the underground world. Great antogonists the nerubians with strong old gods stuff. Great revamped zones. BUT... if you accept suggestions IMO there should be some Argent Crusade everywhere (after wotlk, they are likely one of the dominant force of the continent) and good nerubians fighting against the old gods' invasion.
Maybe we could need some new heroes for each faction and some forgotten ones.
However, excellent work.
