Ehm sorry but FF14 was a massive failure, they had to re-invent themselves completely and make a restart.
anyway as to your other point. We dont want MMO's to fail. We want more good MMO's we could play instead of the half arsed cash grabs we keep seeing.
People are upset because they see potential being wasted on the thought that MMO's make easy money instead of quality MMO's being produced that people are willing to spend there time for the next X years of there life on.
