Guild Wars 2

Here is a fun idea. What if the game made something similar to instant adventures in Rift, but with a Guild Wars twist. Basically, an open world zerg teleporting rapidly from event to event, with a special queue for it.
It could have bosses, heart quests with a group twist, puzzles, etc. A huge mob running, teleporting around doing rapid fire events, and having a blast doing it.

+1
maybe the activities guy will offer this as a new end game dungeon hybrid. big group gets teleported to random locations (instanced of course) where the difficulty is greatly increased. to hell with jumping puzzles though. seriously.
