smilkovpetko is a retard. He's posting literally the total number of characters that existed on a server ever, including bank alts and all the level 1's that people rolled and then abandoned, etc. No Blizzard vanilla server ever had 10k or 14k people online at the same time. The servers had enforced population caps with login queues, and 10k online would have been literally impossible to manage with the server architecture they were using back then. 10k people isn't even manageable in 2015, as can be seen on Nostalrius now. What on earth makes you think it was manageable 10 years ago?
Even if the bogus statistics he's trying to claim were accurate, who cares? He's actually arguing against his own point, saying that 9.7k people supposedly online over a 24 hour period for AQ CRASHED THE SERVER. So how is that good? Huh? He's literally pointing out how terrible and unmanageable something was as an example of why things should be that way now. Fucking dumb.
Same goes for the argument that EU vanilla servers had Russians who never interacted with the English-speaking players. So what? How is that good? IT'S NOT. A good server has a consolidated community where all the players can communicate with one another. We already have half the damn server we can't even talk to ingame. It's called the opposite faction. I don't need my own faction to have thousands of players I can't communicate with. That's just stupid. There is nothing fun or useful about it. It just sucks. Even the Chinese players want to have their own server, and there is absolutely no reason not to give them one.
