Never played Guild wars 2?

Megaserver. Which Guild Wars 2 uses. They didn't at first because they were still working out design kinks (which they said at launch. basically "we want to have a unified server system like our previous game, but it's not ready yet so we'll be using a server system"). And remember this was something the development team wanted from the beginning and it STILL took them until long after launch to get it right.
Then we have ESO, which also uses a megaserver...and anyone whose played can tell you the instancing problems that game had and still has.
In short, our server system is another symptomatic problem of 1.0 being behind the times when it launched.
