Biggest private servers, by expansion

**SuperCPU** · 04-25-2015

Hello people,
I would like to ask which ones are the biggest private servers (biggest population), grouped by expansion.

I've only played Classic WoW lately and I think in this category the biggest are: 1: Nostalrius Begins, 2: Feenix, 3: Kronos, 4: VanillaGaming.
Only Nostalrius Begins and Kronos report their number of players (using /who):
- Nostalrius Begins: 5,400 players at peak hour (20:00 GMT) and 2,400 players at lowest (8:00 GMT) - at least that's what they claim
- Kronos: 1,200 players at 20:00 GMT and 340 players at 7:00 GMT

Feenix claim they have 4,000 players (only at peak hours I guess) and VanillaGaming - probably around 400, according to some claims.

Cataclysm and WotLK - I've only played on Molten-WoW for a month and I think it's probably the biggest - but I don't know which other big servers exist
TBC - I've only heard about Excalibur.
MoP - Molten has MoP but I never played it - still a lot of things don't work, from what I've heard.

Ah, and if you know any new servers that will launch in the future, I would like to know about them, I don't want to miss the moment of their opening, it's such a great feeling to be there.

For the moment I only know about Classic Warcraft
