If you do the /dancenew with the Assassin or the Ritualist and shadow step away your background dancers will stay in their place. However, if you move, they will disappear.
Collector's Edition dances
The Nightfall Collector's Edition dances resemble the African tribal dance in Coming to America.
To access the special dance emotes packaged with the Collector's Edition of Factions, use the /dancenew emote.
The /dancenew command is available to all characters and classes, even Prophecies and Factions, with or without the Collector's Edition. However, non-assassin, -ritualist, -paragon, or -dervish characters will resort to their usual /dance routine, and non-Collector's Edition assassins and ritualists will run through their /dancenew routines without the shadow/spirit backing dancers. It is therefore possible to synchronise /dancenew routines even across classes and indeed different Guild Wars products with /dancenew *. /dance * and /dancenew * will not sync.
For assassins and ritualists, the /dancenew routine has certain differences to their usual /dance routines, including the "summoning" animation at the start and a few minor in-dance variations. For instance, during the male assassin dance there's a part where the dancer is pulled upright like a puppet on strings and is then "cut" from those strings - In the /dance, the assassin does this himself with his own hands, while in the /dancenew he allows the two shadows to do this; one pulling and one cutting.
Assassins and ritualists can display both their Divine Aura and their Collector's Edition dance by doing /dance followed by /dancenew. However, this does not work for the Paragon and Dervish with the Nightfall Collector's Edition dances - the /dancenew will simply replace the old dance, including the glowing effect.
Both the Nightfall Collector's Edition dances (for Paragon and Dervish) will keep their animations going if you do another emote. They will continue until the second emote ends. If a looping emote such as /guitar or /bowhead is used, the disco ball or confetti will remain indefinitely.

The male elementalist dance combines parts of dances from two sitcoms, Friends and Seinfeld. It starts out with moves from "The Routine," danced by Ross and Monica Geller in Friends, and culminates with the "Dry Heave," performed by Elaine Benes in Seinfeld. Only the "Dry Heave" portion of the dance repeats.
The female elementalist dance is mostly a representation of the Hawaiian hula Dance.
