Initial World PvP Information

For Wrath of the Lich King we’re gonna have a full non-instanced zone that’s about roughly the size of Westfall; Lake Wintergrass is right in the center of the continent of Northrend. It will be massive; it will have various points of interest and objective to spread players out, so that they are not all on one spot, and we’ll also incorporate our siege weapons and our destructible buildings into that. Our goal is, we felt like, with Burning Crusade, we have done some things right and some things wrong with world PVP.
Looking at Hellfire Peninsula, it was too fluid, it was changing hands too fast and it didn’t feel like it had an impact. And, then, we felt that Halaa and the Spirit Towers were more in the right direction of how world PVP should feel. It should feel chaotic and frenetic, but with an impact and an ending that feels like it has changed the world a little bit. Not that we’re gonna copy those exactly (Halaa and Spirit Towers), but I look at those as things we did right, and, hopefully, we can apply those lessons to Lake Wintergrass; really epic, like effecting-the-whole-continent type of PVP zone.
