I'd kill for access to a lot of other races' poses but I have my doubt that they'll honestly implement even your request, sadly. I get the impression that they don't want to fill up the emote menu with tons of new emotes, expressions and - on a different level - poses. The more idle stances they add, the more you have to filter through the /cpose option unless they change the system to allow you to be more specific.... and I imagine that'd be seen as tedious.

I'd love if they made all poses available and you could specifically select which five(or however many there are at the moment) you want to appear in the /cpose cycle for whenever you click through it. Not an idle stance but I realllly want the female Highlander sitting pose!
