I'm sure I'm going to regret putting my 2 cents in, but here goes:
The way I understand it, the purpose of drum corps is to provide entertainment. DCI/DCA/etc. assign rules in order to entice corps to not go on the field and perform something painful to watch/hear/experience. If I understand correctly, the addition of these electronics rules is supposed to help the corps increase entertainment value by giving designers more to work with. Have a wicked synth solo, or have certain parts in the pit more audible, that wouldn't be audible otherwise. Maybe have a synth provide sounds that the corps otherwise would've been unable to produce? I'm sure this added voice amplification would've made the Bushwackers' lives a bit easier this past season. It was near impossible to hear what was being said onfield for most of the season. I recall a few other shows among the years I've been aware of drum corps where the new rules would've been a great help. Please allow yourself to be entertained, because that's what those corps want to do for you. I never enjoyed marching a show I wouldn't want to watch myself.
