the whole wow PVP system is completely and utterly broke - instanced BGs that have no affect upon anything, dead world PVP, a completely nonfunctional arena system, a bizzare welfare epic system, etc. Warhammer has a very well done and thought out PVP system, and it is going to suck in a ton of WoW players which will force Blizzard to take notice, and eventually Blizzard will redesign so PVP is melded into the game from start to end in a cohesive fashion. Sadly its going to take 2-3 years at least and probably not until the next Blizzard MMO.

The original core design team of WoW really are PVE oriented guys and it shows. Hopefully they have hired new blood in the last few years that can shake things up.
