You know....the constant complaining towards Sara's face is getting to be kinda offensive.

Well, may be you should take into consideration what lies behind this bullshit. I risk to word it poorly but I'll try.
What we actually have here? We have two sides implying pressure on each other. The more pressure goes from one side the more comes from another because 'those others still didn't get it'. Even those who were completely indifferent at first become passionate participants because topic getting wider and more thought out/wilder arguments are thrown in, invoking various 'wtf' reactions.
Yes, it is a cycle. And it revolves around problem that is there. Yes for some people it's not a problem. For some it is but not big enough for that much of a noise.
The thing is, so much noise doesn't come from the problem itself. For example - and I'm fully aware that I can be wrong - I do think that you said that Sara is perfect only because you have seen too much attacks on her. It is a protective reaction. Probably you simply liked her at first and when you felt the need to protect her you liked her even more - to the point when she became perfect.
Something similar is going in the heads of "ugly" camp. Only they protect their comfort zone. And like you (not every woman needs to be hot chick to exist, yes) they do have their point too. As I said they want to live through space adventure. Great experience is what they play the game for and this greatness is lessened when characters with whom they are supposed to form some kind of bond look unpleasant to them.

I'll put it that way: you do a "noble" thing and protect diversity and those people do a "normal" thing - and protect their comfort with experiencing Bioware story. You think their point is of idiots and pigs and they think that your point is shallow 'diversity for the sake of diversity' and agenda. And when they see another one unconventional character and express their frustration, saying "A-ha-ha, eat this you pigs!" doesn't help either for them to accept your diversity nor for you to stop hearing those irritating "ugly!"  cries.  'Patriarchal mentality' lesson stays unlearned and frustration grows.

If there's one thing BioWare fans get used to, it's the people who genuinely believe anything that is not exactly what they want is flawed and wrong.

It seems they edited the character kit. The face changed, improved in my humble opinion. I guess BW too felt that the previous version wasn't entirely ok.

Have I ever told you the definition of... a joke?

Never mind Sara, why can't Scott either shave that peach fuzz off his face or grow a hearty beard...

...god damn I hate his fluffy cheeks

The problem those of us in this camp have is that the animations are just enough to cause the uncanny valley effect for us, which makes Sara seem almost but not quite Human in her facial animations and it becomes really unsettling. It's not that they aren't perfect as much as they just hit that area where it becomes very noticeable.

Though BioWare has already said that they're working on polishing up the animations.

Exactamundo!

I like Scott's face. He look's a lot more 'normal' than Shepard did, like an attractive average Joe. I'm also an advocate of cheek fluff, so lay off 

And as you stated, you can change her look if you want to anything and because of that its not a problem. So what I said still stands.  The facial animations however cannot be changed manually and need to be corrected through a patch. That is a real problem relative to how a customisable character looks.... The fact that that's what people are pointing out is really very dumb. It takes 2 minutes of your time to fix her appearance as opposed to a gamewide glitch in animations.
