It's not so much uncreative as simply more common. Given that we only have so many ways to change bodies one way or another, it's just the easiest way that people have access to most easily. Urianger in the story is shown to have glamour ability. Illusion magic seems to be one that can be used to fudge a lot of things, and it's a more feasible fallback than say, actually using an in game fantasia. It's simple to say someone went to a magus that specializes in glamours; the Halloween event is a good example of some amazing glamours that can change the appearance of not just race, but even into believable monster species. Someone who dedicates their lives to that kind of magic would obviously likely sell it to make money, selling disguises for criminals or spies, or fleeing refugees, or races that might not be accepted right away.
Another consideration is that the idea of rarity is based entirely on PCs. Hydealyn is a big, big world;Â and three people out of what are probably millions, or even billions of people would technically be considered rare in terms of numbers. But most don't consider the world full of billions of NPCs living every day lives as part of the number involving PCs. Admittedly, meeting three in short order could be considered a highly rare coincidence in and of itself, but not entirely impossible by the numbers. Just highly improbable.
When I changed one of my characters to an Au Ra, she'd already died IC, so there was really no conflict there. However, I'm fine with accepting any reason a person has..a curse, a glamour, forced transformation magic, Allagan machinery, surgery, Fantasia slipped in your tea, Echo transferal, whatever works for them as long as it's proven to exist in the world itself already.
