We can't

[Daralii]

The engine for this game is a basically a polished turd.

I'm not saying that with any ill-intent, but that is basically what it boils down to.

Something this game has in common with WoW, which runs on a modified version of the WC3 engine with a mountain of code that no one can decipher because it was written by a different staff over a decade ago. I can only assume that it boils down to Crystal Tools/Luminous Engine being a lot less malleable and/or the XIV team being given fewer resources.
