Warhammer Online's "Producer's Letter" Details RvR Changes

Warhammer Online's latest "Producer's Letter" details some of the changes for city siege RvR (Realm vs Realm) in patch 1.3.1 and what kind of experience players can expect to encounter when they try to take an opposing factions main city. Several of the mechanics involved in taking an enemy city have been re-worked to give a new kind of experience.

One of the biggest enhancements going into this patch is the new approach we have made with our end-game city siege experience.  After months of feedback from you, the players, and our own personal experience playing the game, we realized we needed to step back and reevaluate the city siege mechanic from beginning to end.  Specifically, how can we make the city siege experience something players will strive for?  How can we reinforce RvR in the endgame and not RvE?
