A thousand times YES. I remember back during BETA testing I had suggested several times to give us the option to choose a "mood" that would affect how we perform emotes. A big example is Keepers of the Moon, a race that by lore is brooding and prefers solitude. I would've liked to be able to set my character to give quieter and less happy-like emotes than she does. The facial emotes are "ok", but they last too short (not sure why they didn't make them toggle-able like /sit), and even then, the body language is all wrong for my character to look brooding and well... "adult". An option to give us different moods and stances would be really great.
