There hasn't been a stress test of this size done yet.
We did a stresstest on the developer server before the game opened. We needed alot more mobs to crash the server then there were player today. I know that there is a difference between mobs and real player but we had to spawn like 5-10 times as much actual created characters.
There are people who actually donated fucking real money. All of them are in their right to complain.
Yes, but you not.
