I died a little bit inside when I thought about posting this, but I just have to do it.
Wingergrasp, a true RvR zone.
Sadly it is not found in Warhammer Online: Age of Reckoning. Wintergrasp will be part of World of Warcraft's upcoming expansion: Wrath of the Lich King. The notes on Wintergrasp are the things I expected out of WAR's RvR areas, but sadly have not found.
Now, just because Blizzard is beating Mythic at their own game with a single zone, does not mean WoW is suddenly a RvR game. Wintergrasp will suffer the same fate in WoW that other open world PvP objectives have suffered: Wintergrasp will not be worth anyone's time compared to battleground or arena grinding.
So, Blizzard gets a +1 for open world PvP, but a -1 for letting instanced content dominate open world content. Mythic, take notes, learn, and come December; patch 1.1 better do SOMETHING to open RvR zones other than giving more experience per kill. Give us a fucking reason to be there other than the keeps.
