I love this idea, some of my favorite sections in both LotA and WoD is the Atomos fight where we have to break up into our individual teams and help the other teams by pressing buttons. It's simple now, but if SE could impliment these types of mechanics into more dungeons that would be great. To often are the dungeons, run straight, fight a boss, rinse, repeat. I want dungeons with a little more variety, and bosses too. Maybe have one were a player needs to be standing on a platform for some reason, but the player who is used "should" change based on the bosses demenor or something.
