I've played plenty of games with five players. The danger for me was that we would slip into "everyone must have their say" mode. I want everyone to participate, but not everyone can have a scene about what's going on in the current scene. Not everyone gets to grandstand about every little thing said. Participation is best when it's sharp, precise.
In fact, BE is a very tough game to play.
