I do not liek the idea of regional (NA, EU, ASIA, COeanic) servers, perhaps language based (english speaking, Dutch, JApaneese/Asia) but We have people from EU that are english and french speakers, and NA ENglish/Spanish speakers that play together and don't want to split up). Proper data serves can limit lag and let us stay together. How FF online is meant to be.

May want to check into CLoud data serving, and Fast C centers, it is already used.
