I could go on about the booger monster or a simple mind-control guy with how FFXIV still wouldn't have all the pet classes, but that would just be mean. I will say this though: adding a class just so we can finish off the collection in the same way you might want a stamp to finish off your stamp collection is a very weak excuse for adding something.
