Only part I say they failed on this Welcome Back Campaign is they still had the servers all closed...
Some people wanted to start new characters on other servers to see how much the game changed and also be with other friends on other server and because the servers are locked due to the stupid Uldah Zone A issue they are playing solo on other servers. They like the new battle system but they aren't getting high enough level in 10 days time to even try to attempt Ifrit, Moogle, or easy raids like Totorak...
