If we were playing, say, World of Warcraft... I'd be more inclined to agree with you.

But the artwork of Final Fantasy is just so much better than World of Warcraft's. Making a character with a look you like is just more important in a game where the artwork is better.

It annoys me when it happens to me (for obvious reasons that I will not dispute are extremely petty), but look at it this way... For you, it is a temporary upgrade. For them, it could be an item that they use for a very long time.
