We've been receiving a constant stream of news from the ongoing Worldwide Invitational in Paris, France, and we've gotten hints of changes coming to the game that promises overall improvements to PvP. In the developers' panel discussion, we learned of a Shadow Priest talent called Dispersion, which Blizzard hopes will allow the underrepresented Shadow Priests to become more viable in Arenas. The dungeons and raids discussion yielded plans to further continue the purchase of PvP gear through PvE, such as from reputation.
The panel at the WWI earlier was cleverly titled "PvP Game Systems", where Tom Chilton and Corey Stockton discussed Lake Wintergrasp, new Arena maps, and the new Battleground. It was a rather uninspired panel compared to the previous ones, revealing very little that anxious players didn't already know. Because of the suspiciously lengthy yet predictable presentation, very little time was left for questions (of class balance, I bet), although a few good ones were asked -- and surprisingly answered -- during the session.
