Wouldnt it be fun if nostalrius launched a new realm for 6 hours, where everyone just started at lvl 1, and a few moments later, they teleported all players to dun morogh, in the starting zone. Removed all high-lvl guards, made the 1-2 graveyards friendly to horde aswell (so they have equal corpse runs) and then just let chaos take place.
If announced on forums, about 1.5k players would attend, considering 1k ppl came to kryll event.
Hell, it takes 15 minutes to make that server, about another 15 to do modifications/remove guards, and some GM attendance to teleport the players (or enable some macro where when people whisper you a specific word, the teleportation command is casted on them)
Chaos would take place, entertaining chaos, hundreds of lvl 1-3 of both sides fighting on the icy valleys of dun morogh.
I mean why not, it could be hilarious once in awhile, takes little effort (ive run vanilla servers) and is really fun

Honestly, why not
