Yeah Blizzard are showing pure arrogance and disrespect with the amount of servers they've got prepared. Which almost invalidates the purpose of picking a server and nickname. Okay there may not be 10 million players playing Classic, but 12 servers can't handle even 1 million, 500k or even 200k people.
How exactly are they doing their math on this? Are they expecting there will be no more than 100k people per region playing Classic? That's crazy!
