ArenaNet:Guild Wars 2 suggestions/Orbs

(Discussion)
Orbs are objects that are randomly put into every mission. Once you pick it up and it gets put in your inventory and you activate it, it causes something to happen. (ei: There are twice as many monsters). Some could just be for fun (ei: You are twice as short). You could collect them and use them. When used in missions, they effect everyone.


 * Why this is a good idea
 * Adds more to the game.


 * Why it may not work out
 * Someone might activate one in a mission and no one could do anything.
 * Tremedous griefing potential.
