I'm doing Zerith-var's quest chain and going into dialogue with Cantor Krin'ze is so discombobulating.
My Nord warrior has all sliders maxed, especially for height. She barely comes up to my waist. Yet when I enter dialogue, all of a sudden my 6'5 Nord is barely three feet tall.
The same is also true when I (albeit rarely) play on my Wood Elf, who is about 5 feet tall, you'd think I'd have to look up when speak to Queen Ayrenn, but nope, all of a sudden I am 30cm taller and at eye level.
I wish they'd add a camera option that either doesn't rip you out of your perspective or at least takes character heights into account.
