You do not get it.

This game was released way too early. Now, they are basically redesigning the whole game. What we are doing now is playing a game while it's been developed. Redesigning the whole game takes a lot of time and testing it takes even more. If you don't want another volume of broken FFXIV you want them to take their time testing.

To keep our interest in this game while they are doing this long process they need to add content.

Quest, sidequests, grand companies, raids, events, these stuff have kept me interested in this game while I'm waiting them to fix core mechanics and stuff.

If there wouldn't have been any content updates, I would have already forgotten this game.
