Special emotes?
Painbringer
While waiting for the Emperor I noticed a few people dancing with special things like spot lights from above and some had what looked like the head of a deer in a seal of light. How do you do this??

You get the Spot Lights and the Back-Up dancers from the collecters edition of Guild Wars Factions. As for the deer, you get them for being r3 and above. Check this link: http://gw.gamewikis.org/wiki/Rank
