Slycer on BG posted a little more of what Krael described, and it ends with this amazing gem:
Crowning content of your first major expansion. Expansion itself delivered a little later than expected, and the raid itself will be delayed a month later than that.
Not enough time to test it all the way through, gotta move on to other content! *laughs*
I see. And this applies to the highest difficulty content like the fourth section of Alexander savage?
Yoshida: For the third and fourth parts of Alexander savage specifically, we tested each phase. The FFXIV battle team is made up of some pretty good players, but these aren't world class players. It would have taken longer to perform adjustments if we tested as usual, so we tried to shorten it a bit.
So the release would be delayed if they tested until they could clear.
Yoshida: Since the development cycle is limited we had to proceed with the development of other content. You could sort of say we've cleared it completely through (laughs).
