Since I don't know the history with the "hyurification," was the process of basing all the meshes off of a Hyur base mesh something that was done from the very beginning in 2.0, or was this something done with the graphic updates for Dawntrail? If it's recent, I worry that this might prevent them from doing larger changes if it's not compatible with that mesh conversion.

It also sounds like this might continue for a few more patches... for folks that don't have easy access to translation, the link from the earlier page was YoshiP saying this during the liveletter:

Final Fantasy XIV "83rd FFXIV Producer Letter LIVE"
(1:31:34-1:32:16)

"Well, we've been receiving a lot of detailed graphics updates from all over the world, and we're going to be making adjustments to them, especially to the characters, as I mentioned in the text the other day.

Of course, there are some things that can't be made in 7.1 alone, so we're going to let you know that these items have been added to 7.2 and we'll be working on them properly, so please check that out too.

However, it's all very nuanced, so if we just show you screenshots of what's going to happen, you'll end up noticing whether it's right or wrong, so we'll be delivering patches with thorough adjustments, so we hope you'll check them out and give us your feedback."
