Dwarves, and enkis simply look around, which is nice... Because its not something so drastic that it could be misunderstood as an action.
But ynwnn's stretch, ynwnn females bend over, klyros seem to never be able to satisfy that itch on their necks, and dermorian males always have itchy ankles. This is annoying, and really unnecessary, wouldn't a simple look around animation like fenkis or male dwarves work better for an idle animation - really?
I was brought more aware of this during a little espionage mission where I was hiding behind a tree, as if it weren't hard enough to hide a ynwnn alone, I had to deal with him stretching his arms out every now and then, giving away his location.
These 'idle' animations that klyros, ynwnn, and dermorians do are hardly what I'd qualify as Idle, more like an action all on their own... I'm a guy who has many pet peeves, but really I think this is just something that the devs should consider changing...
