First off, I'm not even sure where suggestion a new emote goes in terms of forums, but anyway.

I would like to suggest a new emote, waltzing!



(Disclaimer: I don't know much about waltzing itself)
As the name of the emote suggests, typing '/waltz' would make the player waltzing by his/herself as if their partner was invisible (a la plague knight). However I would also like to suggest right clicking a person and request to waltz so that the two are waltzing together. Wouldn't that be dandy? Waltzing on the roof of your home in the pale moon light.
