I detest CRZ. My realm's Elwynn Forest gets lumped with Moon Guard. So now any time I'm in Elwynn, all I see is all the ERPers and their general chat looking for cyber. It's buggy, I've been dismounted or had friends dismounted crossing zones and the already hard to get rare things are nigh impossible now.
Sure for low pop realms it might be good, if they want it. :| If.
