I'm in the dark regarding the technical aspect of what incorporating a brand new graphics engine into a game entails. However, I have a simple question that I would like somebody to answer.

There is a lack of enemy diversity in XIV as you all know. Is SE holding back on adding new enemy models because they would have to re-create them for the current engine on top of creating them for the new one? Or would the new engine just apply changes to the rendering of the current assets on top of adding new possibilities? 2.0 is quite a long way off so it would be nice to see a decent diversity of enemies roaming the fields of Eorzea. If we can't get brand new models, perhaps tweaks to current enemies would be nice: color swap, height change, etc. I know we have a few alternatives to current models, but more would be nice
