I'd really like to see a lot of the emotes be redone.
The Lalafell M wave, for example, is horrible. It's too much I can't even bring myself to do it when it should be one of the most frequently used emotes in the game.

It looks i'm trying to flag down a rescue helicopter after being trapped on a deserted island for years.
And the Galka and Hume emotes are just horrible.

More serious, dignified emotes please...
