Could Tol Barad world pvp help save Neltharion?
Why not have the remaining Nelth pvp'ers agree to spend a lot of their free time running around Tol Barad fighting each other? Try to have a gentleman's agreement where solo guys aren't attacked by groups. It could end up being a lot of fun, like it was on retail. A nice thing about world pvp is that just the possibility of action at any time makes the world and thus the server seem "alive," even if nothing ends up happening on a particular occasion.
