It's all about the fan service. I recall Yoshi P. mentioning several times recently that FF XIV was meant to have fan service in it from other past Final Fantasy titles. Crystal Tower from FF III being brought to XIV as well as Atomos and his new updated model from FF XI that many fans remember, along with the goblins from XI, Magitek armor from FF VI and much more.

It's fan service to make us happy and remember the games from the past that we enjoyed. Take it for what you will.
