Mm. In my instances, I generally only fantasia a character I'm not inclined to play anymore because the idea fell flat in my head, or what I was doing with them isn't really working out and there's no way to recoup it. My Au Ra male, Takeo, I actually made as a Hyur way in advance for Au Ra change. I kept him level 1 till Heavensward (since I was mostly doing things on my main), and now I've changed him right proper. I changed my other Miqo because she died IC, and renamed her. I don't change race or gender on a lark, but sometimes it's fun to do it temporarily for comedy purposes, if you want to run a silly story arc, because not *all* RP has to be srs bsnss, after all.
Most of what I create is fixed from the get go, unless something really changes that. I think if they ever come out with half-breeds though, I might change my main into a half-elezen, because in his original iteration when I created him ages and ages ago in tabletop D&D, he was a half elf. If it happens, I'd figure out some way to explain it, but I doubt we're going to see halfies for a long time, if ever. But that's sort of off-topic again, apologies.
