I don't mind fans chanting what they want. If they want to chant "what" during the first bit of a superstars promo, then by all means. After about 2 mins straight it gets very old and prevents one from being able to hear what the superstar is actually saying, plus it makes the wrestling show annoying to try and watch from home. I would prefer superstars to just continue talking over them without a pause so the fans don't have a point to say it. Construct your dialect in a way that results in longer sentences without so many dramatic pauses will prevent the fans from having the chance to say it, and will also eliminate that "reading lines" aspect that some many superstars come across as doing when cutting a promo.
