The membership should never complain about staff- unless they're being subjected to something hurtful, cruel, or unusual, that isn't their place within the organization. You also spent three years getting to know them personally and joking around with them, of course you're going to think they're great.
Additionally, as "incredibly talented" as you may be under the assumption that they are, it is well documented via recaps and many fan's opinions on here that they may not be as hot to trot as you suggest...both from a design perspective AND a technician perspective. Note that I am NOT saying anyone that is on staff there or formerly on staff there has no talent, just saying that the past few years haven't provided a whole lot of support for your argument.
As a drum corps fan and music educator I expect to be entertained by the shows that I shell out a great deal of money for myself and my family to see. I WANT to get out of my seat and throw babies and buy a bunch of shirts are the souvenir booths, but I refuse to do it when I am extremely bored by a corps on the field. The Troopers are a fantastic organization and historically they have had some seriously entertaining shows. But as of late it's been nothing but extremely droll and boring shows that have maybe one or two effective moments including my favorite effect moments- PLAYING REALLY WELL! I applaud the administration for finally realizing that there needed to be a change and are putting it in motion. Make me excited and don't make me think about buying a shirt- force my butt out of the seat by producing an excellent show.
With all of that said, I admire your defense of the staff that probably taught you many things not only about drum corps and music, but life as well.
