Leerooooooyyyyyyy!
De mentions how City of Heroes/Villains provided some insight into how fight scenes can go when everything is not perfectly orchestrated. Which is brilliant, since everyone who's played a MMORPG knows how things rarely go as scripted or planned, and how that can result in defeat (or near-defeat) with much more excitement and interest (and frustration and angst) than something that goes just how its choreographed in advance.
So, instead of the suggestion that "If things go slow, have someone walk in with a gun," it's perfectly acceptable to say, "If things are going well, someone gets cocky and runs into danger" or "someone wanders off for a bio break" or similar hilarity.
