According to OP, you can only use the emotes "while standing still". I don't think any pvper would ever give up agility like that
So, why would the developers spend time, money, and resources developing this for such a small amount of damage with the added bonus of removing a player's agility?
Because this game is all about creating stories and moments, and it's a lot cooler to shoot someone with finesse vs the default shooting animation; and adding a bullet here and there to certain emotes isn't exactly state of the art technology.
Of course it wouldn't be used in actual combat, but it would make for fun moments when players meet each other.
