I have high hopes for world pvp in Cataclysm.
Many zones that were pretty much one-sided will be more balanced, with enemy outposts sitting really close to each other (as Holycola pointed out in another thread). Confrontation will be inevitable.
Now, what really has me thrilled is the situation with Ashenvale and Southern Barrens.
Having played a night elf for a long time, I feel compelled to go to Ashenvale and kill as many horde as posible to make things right and kick them out of MY forest :P . And I´m pretty sure many horde feel the same way about Southern Barrens.
I know the old Hillsbrad Foothills pvp style is gone, but I really hope both factions answer this "call to arms" and contribute to spice up a bit our world pvp.
So, will you fight back for your land?
