I only played WoW for a little while after CRZ came in effect, and the main problem I ran into was that gathering nodes were all shared, so only one person could gather and when they were done it was gone for everyone. Which meant a dearth of resources as they were now suddenly shared across multiple servers. Over here, gathering nodes work differently, with everyone having access to their own instance of one, so that problem at least won't happen as there is no competing over nodes.
