Except for the fact that a quick google search will tell you that Eve's Tranquility "1 Server" is actually a server cluster of 70 to 100 servers.
Every MMO uses multiple servers to accomplish just about anything so pointing this out is not really helping illustrate your point.
In what you quoted from SE they even stated that each WORLD SERVER was comprised of multiple servers. I think the point the other poster was trying to make with EVE is that they could deal with 60k people on a single WORLD SERVER (regardless of how that infrastructure/instancing is setup) while the FFXIV WORLD SERVER each only holds 5,000 max.
Many times you can login to EVE and in a single ZONE they will have more than 10% of the entire WORLD SERVER cap that Square Enix has established.
