There's very few people on SWF wanting people cut on these boards; trust me, I've got as many posts speculating smash 4 short of anyone not named Omega and possibly Oasis. Everyone else I had way more posts than.
And few people want characters cuts, and if they do, it's 3rd party characters, or characters like Wolf, Toon Link, and Lucas, who are semi-clones or clones.
As for the roster, people want improvements. When characters are flawed in fundamentals or balancing whether it makes them too strong or too weak, people want changes. Captain Falcon was weak as hell, so quite frankly, he should go back to being awesome like in Smash 64 or Melee. Ganondorf is fundamentally flawed as hell (in terms of being a Captain Falcon clone, which makes minimal sense), and he should finally get at least a few unique moves.
As for your Brawl tournaments, local tournaments and major tournaments are a hugely different deal. I once made it to the final 32 or so out of thousands of smashboarders in an online tournament, and I did fairly well at local tournaments when I played Brawl. But man, the big tournaments will eat you alive.
Also, you're talking about your way of playing as if it is superior, which is laughable. Smash bros is about playing a game however you want to play it, wherever you want to play it, whenever you want to play it, for whatever reason you want to play it. To tell people to do something a certain way over such a free and unique and option-filled game like smash to play it one way or another when it doesn't involve you is stupid. To act otherwise is to be a simple-minded child. I'd no sooner not tell 4 friends playing with all low tier characters, items on very high on Hyrule Temple not to change how they play as I would a match up of Hungrybox and Mango with no items, Fox dittos on Final Destination (and for the record, I've witnessed both live in person).
If the franchise was meant to be played one way there would be no options to play it another way, and it would be specifically designed to be played that way. Also, Sakurai would say smash is only "x and y" and the entire alphabet and every number like he says it is.
