I like how Wow is gonna have pvp. Instanced battlegrounds where you are flagged for pvp when you enter, arena's where you can duel members of your own faction or anyone else you want, you get flagged for pvp when you attack an npc or try to enter an enemy faction city. Of course that's on the pve servers since pvp will be 24/7 flagged. You can also use a command to flag yourself for pvp on the pve server if you want and it resets after 5 minutes of no combat. I loved the stress test beta except I didn't want it to end. It will probably be the first game I've ever went to the store to buy first day it's out, usually I pick a game up when I feel like it but this one will be had first day. Also they changed it now so that undead can't speak to alliance so the sides can't communicate now, though I have a feeling you'll be able to learn the languages since they were listed under talents during the stress test. Add in special rewards for doing well in pvp and hero classes and it should be fun for a good long time. I've also heard mention of destroyable buildings in the instanced battlegrounds but haven't seen any official word from blizzard on that yet.
