I voted for Divine Purity, because I don't like the automatic conflation of angels and demons with divine beings.
The big thing for me, aside from the whole re-skinning thing, is just that's overtly fantastic. It might be fine in Sigil or Waterdeep, but if you're trying for anything remotely low-fantasy in tone, the big glowy wings are working heavily against that.
I know, it's a fantasy setting and there are elves and wizards and stuff, but wings are a step beyond that. Elves and dwarves, or even dragonborn, are more like fantasy-world substitutes for foreign cultures; just having them present doesn't cause the world to play out in a fantastic manner. Even wizards and clerics are just normal people, who are otherwise indistinguishable from anyone else during the 98% of the time when they aren't in the middle of casting a spell.
Having wings is like playing as a dragon, or a talking dog. It's very clearly a high-fantasy thing.
Just to be clear, I know you didn't-hence the quotes. Probably should have use a wink emoticon instead of the big smile.
But as to pseudo-medievalism, I hope you know winged divine servitors isn't the exclusive purview of the West. They exist in Hindu iconography, as well as Assyrian and other eastern cultural/faith traditions as well.
At any level, even epic. Without getting too deep, because they are goofy. Also, because I don't like playing up the inhuman aspect of Sorcerers that much. A class is a class and a race is a race; the lines between the two shouldn't be blurred too much.
Also, what [MENTION=6775031]Saelorn[/MENTION] said.
To turn it around, why would you want them?
