Cross Data Center Party Finder?

[Bourne_Endeavor]

Cross Data Center will never be a thing, it defeats the purpose of having servers in different regions, and puts load on services that simply can't handle "all players" logging in at the same time.

Uhh, Yoshida has outright said this is something they want to do eventually. Furthermore, people aren't asking to connect to different regions, just all the Datacenters in their region. So Aether, Primal and Crystal players could all be in a party together. As Barraind mentioned, WoW did this already. If Blizzard figured it out, why can't Square Enix?
