To answer the OP, I don't think that anything was removed to prevent anyone from being offended. I do think, however, that character design has evolved in response to the real world. More female gamers ARE becoming more prominent, and a lot of people are referring realism to perfection.
Personally, I do find it irritating, but not offensive, when surrounded by barely clothed nude characters whose armor SO does not protect them. But that's because it's silly rather than any baggage. Armor that leaves your vital areas exposed in order to make you look sexy is dumb. That goes for men and women (I'm looking at you, Bull).
Facial features wise, I still find Cass to be an incredibly striking woman, and I do hope for more like her, and I don't really understand why some people don't find her attractive? She is striking and is so full of character and personality. I just love her.
Vivienne isn't romancable, but I think she's beautiful. I guess the lack of hair is a put off, but I think it makes her look exotic.
I can see how Josephine isn't to everyone's tastes--she's a bit oddly colored (apparently I'm on crack and this is normal for olive-skin, sorry!) and her dress is awful.
Sera....honestly I think she needs to be redone. Her face is puffy like she's just been beaten, and there's something really funky about her mouth/teeth. More importantly, she looks nothing like ANY other elf on Thedas.
I wouldn't mind if there were a more conventionally pretty romanceable female, but I really don't feel the options are either lacking, or due to some sort of ulterior motive.
