However, it seems to me that what you're saying by "they don't need to lack clothing" is "I don't like it when they show skin." That's fine. You can not like it all you want. Other people have different opinions on what makes an attractive painting, and it's not your job to tell them what to think.

Anyway, I'm still waiting for someone to post all the images of women in WotC books that are perfectly normal and acceptable so that we may tally them up and determine on what side of the line WotC's art is on. But I fear this will not happen, because it will demonstrate that the art is, in the vast majority of cases, perfectly reasonable. And if that happens, we will have one less thing to complain about. Dire consequences, indeed.
On the first point, I can't speak for anyone else, but I kind of like skin - I just don't like:
A) Wildly and unecessarily sexualized covers (no WotC books fits into this catergory), because it makes it embarassing to bring the book out in public/mixed company. E.g. the old Exalted 2nd magic book, can't remember it's name. Was just... oy vey...
B) More pertinent to this thread, I don't like skin that doesn't make any damn sense. If someone is wearing armour with huge gaps in it, there should be explanation (like they had to put it on in haste, or it's some kinky sacrificial outfit, a la Alias). It's one thing to be as naked as can be when you're frolicing in the woods, or swimming, or whatever. It's quite another to be running into battle dressed in a bizarre male-fantasy outfit for no apparent reason. Druid McBerryeater looks nice, but if she was intentionally wearing the same outfit into a melee/arrow fight, I'd be somewhat appalled.
In general WotC are very good about this, btw. Which is precisely WHY I'm kind of irked about the PHB cover. I mean, we've got dozens or hundreds of good, empowering images of female characters with appropriate skin/no skin (i.e. not hookerplate), so why break that trend on the cover of the most important and common book in the line? Seems bizarre. Of course, it's also bizarre to put two very different Tieflings on the cover, so I really have no idea what's going on there.
As for that godawful blue outfit on the person with the electric whip, maybe to you that's "not what we're talking about", but if so, then we're talking at cross-purposes. "Bizarre sexist outfits" are a subset of "really stupid outfits", and honestly, I'd like to see "really stupid outfits" gone from 4E too.
