This is not so much a change to emotes, but I'd like it if your most recently set emote established your character's "mood". Currently, we can only set how he looks by default when we make him: Case in point, my beta roegadyn had a slight smile, and my current roegadyn has this glare of death. But what if I want him to be happy one day, sad the next?

Though, I'm guessing this would be a "Wait until 2.0" feature.
