I didnt read the whole thin so forgive me if im repeating what others said.
FFXIV was and is a failure .The project was huge and didnt live to the expectations based on many factors .
The game went from Pay to play to free to play in the first month , so not calling that a failure wouldnt be realistic.
The situation can be fixed and that is were game shines.It has a lot of potential , but nothing is certain , so it could keep being a failure or not.Only time will tell.
