Jade isn't too far off from being "pointless". She needs much more uniqueness and story development.
The only reason people seem to like her is because they think she's "hawtt!!1!!" and because they like the color green.
Well, to be honest, when I am deciding on which character to play, personality actually plays a part. I think Jade, personality-wise, is very distinguished from the other female characters in the game. Her dignity and loyalty are the best things about her. I can't get enough of her friendship with Kitana.
