Hi, welcome to the activity. I am fairly new myself, as I started to follow in 2005.
1. Things are that bad, IMO. While attendance at smaller, local shows may be fantastic... Due to poor venue choice, I believe that attendance at major regionals and Championships will begin and continue to deteriorate, especially if DCI keeps the same seating chart for finals!!! $125 for seats on the 20 or the 10?! That's insanity!!!
2. I don't think the point is that the activity is dying because you don't like who won.
3. Electronics are a major complaining point. While I'm sure the kinks will be ironed out in the coming years, I still believe this takes some of the merit out of the hornlines, allowing the electronics to cover up musical gaps that could also be filled in by the pit or hornline. Is this a rip on the kids (my peers?) NO. It is a rip on show design.
4. I am not an alum of any corps. I am a 20 year old student hoping to march what would be my rook-out season next year. Change happens, but to me, it seems like a little too much, too soon. To me, Drum Corps has been a distinct activity from high school bands, although as these rule changes come and go, they seem to be getting closer and closer.
There is still plenty to get out of the activity based on what it was. Horns, drums, pit, and guard. Without electricity. It just involves a little more creativity from the show designers. While some change I believe is good, not all change is good, and at times, parts of the status quo should be maintained.
