Have to ask: which DEV can't dance and just stands there, with their arms crossed and nods their head, turning it slowly from side to side?
Seriously I wish the devs would sell dance emotes on the marketplace. Here's the latest dance emote hitting destiny's mp.
Heck if they can't add more emotes to the emote menu they could at least create emote trinkets that we can stick in our utility belts... Oooh What if we got a new type of Trinket/Consumable hybrid called a "Wildcard"(Basically an item it can go in any consumable or trinket slot... which may or may not be a consumable...) We could then have "Wildcard powers"(Basically an extra power we can use in place of a consumable or trinket, with different ones based on legends powers...)
