Let's just be real for a moment - Neltharion is no longer Neltharion. Its legit Fatalitys realm, a bunch of degenerates who play BGs all day and all night against the same players over and over again, and its these same players who continue asking for changes to the realm. They just wont let the dream go. Nelth will never go MOP because as stated before, it will remain Cata aslong as people still play, which the same 30-90 players still do and always will. What new people want to come join this realm as starters lol? R u delusional? Advertisement would do nothing.
The only way you resurrect this rat infested realm, is too wipe it, and give free starter gear to everyone who joins for the first 1-3 months. Free bloodthirsty, free starter pve, and professions. Only release S9 vicious to give players a whole new meaning to play. This creates economy, community, and a fresh start for everyone, especially new players, and allows them too feel equal to others. Then, overtime, you release ruthless gear, more pve content, so on and so fourth. This is a long shot, considering the devs could careless about this realm, and I dont blame them, why would they?
There are other cata private servers that are infested with aids and broken content, but they practically quadruple nelths population to say the least. If you do this ^ , it'd bring a lot of people here, and the population would grow tremendously overtime.
Resetting nelth and giving everyone there coins to spend would do NOTHING, it'd be hype for a month, IF THAT, before it dies out again.
And to those 4-5 players who want a merge to mop, its already been stated that wont ever happen if players continue to enjoy Neltharion. Those same toxic bg heroes, they wont ever leave, therefore nelth wont ever change.
Goodbye
