Please read the entirety of the original post and realize their stated goal was not met. They were going to connect HYJAL (High pop) to PROUDMOORE (Full pop) because they considered Hyjal to be low enough to connect. Now look at how many servers are below Hyjal and weren’t connected either.
This post is still relevant as they haven’t given us an update here. The only update we got was an obscure tweet stating that the connections were finished with no explanation as to why they completely and utterly failed to meet their stated goal.
Looking at the balance and population of the Kirin Tor, Sentinels and Steamwheedle Cartel cluster, it seems like it would be a perfect match for the Lightninghoof, Maelstrom, The Venture Co, Ravenholdt, Twisting Nether cluster.
The Steamwheedle cluster is slightly Alliance heavy and the Maelstrom cluster is slightly Horde heavy. Both clusters are central time and they’re all RP realms and all those realms are located in the Chicago data center. Merging these clusters would make both those Low-pop clusters into Medium or High ones.
That’s just one example of many that could turn dead or dying realms into thriving, happy realms.
