You can be rdm or sam once you hit 50 so that's not the whole msq. There was the voice actors strike to deal with and then Yoshida got told not to do anymore spendy cut scenes after a certain one from T12. Then there's at least four different languages you have to hire va's for. I'm not sure how it is for WoW or other F2P games in the number of other languages they do the va for. I also don't know how long after the woman who did do Yugiri's voice they took before finding a new person after her death. There is also the change to the cast somewhere around 2.55 and HW which again must have taken time and money.
