I'm dropping in say that as someone who walks the line between being sensitive and difficult to insult, I was a bit jarred to see how elves dress, but in no way was I put off or insulted. My brain just put together pieces of knowledge and suspension of disbelief and the output was to feel slightly awkward, but not put off.
But I will admit that I am not a good judge of what is and isn't sexist when it comes to appearance. I focus more on the societal issues that create disproportional distributions of the populace. Any discrimination, really. So, all I can say here is how I understand the link between depiction of a (fantasy, non-human) woman and the impact that has on real women: Depiction perceived as defining concept that is then applied as a preconception to real world examples. Of this, I can state that the depiction itself is not at fault. At fault here is the human mind that makes the connections between appearance and content (i.e. what the thing they see actually is). This is part of the deeply rooted tribalism that we as a species that fancies itself elevated really need to grow out of.
In short, blame the people making the associations that lead to discrimination, not the representation that intends to say something very different, maybe even a cold hard fact without beckoning any interpretation whatsoever.
Aside from that, I have seen some good arguments around.
In the end I will respect what direction Larian will take, and I trust that their choice will be reasonable.
Being civil is a minimum requirement, but take it from a cheese loving troll that respecting one another even when clashing in debate is a bonus.
Unless otherwise specified, just an opinion or simple curiosity.
