There's plenty of world PvP to be had, ganking raids trying to do the world boss that spawns every couple of hours. I was in a raid group a few days ago. We wiped the Hordies repeatedly (kept killing their tank and healers, so the boss would wreck them) until they finally all had too high a respawn timer to get back before the boss reset. Once it reset and spawned at a different spot, over the hill, we smashed it while they were still milling around at the old spawn location.

Best time I've had world PvPing since Vanilla.
