Is this really true? How can you do PvP if everything is like GW? or is it instanced so that you can only see 40 something people in each zone?
Dare i say it, is it like D&D online?
Nope, people are just being a bit dumb about how the game works. The starter zones, which last up to level 20 or so, are full multiplayer like any other mmo once you get to the city (by level 5 or so). At the inn you have the option to go to 'night-time' which is a single player instance designed to progress the storyline. You can come out of it at any time by going back to the inn, and all the adventuring zones are full of other people. It's not that hard to grasp, there's just a lot of knee-jerk OMGWTFTHSSUXXORS rubbish going on.
