Megaservers break the social fabric of the game that people enjoy about vanilla. Anyone else remember when blizzard said at the beginning of wrath that they wanted to eliminate the concept of a mega server? What a joke that turned out to be.
The community has told you the solution to small and actually dead servers many times. Just MERGE LOW POP REALMS. The only reason you refuse to let go of mega servers is because for some reason you have a severe allergy to merging servers.
It’s not too late to learn your lesson. Give numerous single layer servers, and merge the low pop realms that die when the initial hype dies down. Mega servers are cancer to classic WoW.
