Regular townies turning into spellcasters?

I don't even have this pack but yeah... why is it that all situational clothes, in all packs, are crap? I assume there is a 0% priority to this and the devs just use the same complete RNG code for all of them, basically.

At least with Mermaids there isn't much to screw up (which bikini top to use, that's it), but vampires are just as bad as spellcasters.
