If I can't complete content on my DC without being forced to move to another server, it's dead, especially if it's current content like the moogle tome event. If I go into the Southern Front and there's 4 people total waiting around for duels and not helping on CEs and Fates, it's dead.
I don't care about how it's going to be in 1 or 2 years, I care about how it is right now when I'm paying and playing the game, especially since the forums told me I had to move otherwise I'd never get a house, and now I'm locked into a dead server for 3 months.
