So what does CRZ add? Ganking victims (Meaningless on PvE servers), competition for everything out there from mobs to profession mats, and you can see other people running around, big whoop.
Ooh, almost forgot: CRZ added a bunch of "How did this get through beta?"-magnitude bugs as well, nope, still not impressive...
