How many people would be willing to move to another data center o world? So many of us are invested in our worlds - our friends are here, our FCs are here, those who have houses don't want to give them up. Many of the streamers joined worlds they already knew people were playing that they could play with so gravitated to certain worlds. Some of the influx of the newer players would have diverted to the new data centers, of course, but many wanted to join specific worlds to play with people they knew already played. Not to mention the fact that even if they had chosen to use the servers bought for the OCE data center for EU/US, they still would have had the issues they ran into in getting OCE set up. The installation teams still wouldn't have been able to travel. Squeenix would have had to lease space for the new data centers, or hope the existing server housing was big enough to add more.
