Me and my sister are going to Sephirot.
Sadly, i think we'll lose the money we put into our FC house (We never bothered with personal houses, we just shared an FC house between us), but the latency is so much better (from like 300 something on tonberry to 22 on Seph) that it's worth it.
Will be nice in dungeons/raids to move with the raid and be safe and not die because latency caused the server to think I didn't move!
