Finally someone who understands.No, it wouldn't be as good, and that's simply because the game is too designed around interactables on so many points. You can't see this, all you see is "interactables are bullshit because it's Smash all over."
Interactables are a huge reason why zoning is viable, despite how zoning tools are designed. They allow the game to retain big, situational damage. They help increase the pace. They force stage awareness. As much as they affect already bad matchups, they can help them as well. There are characters designed to take advantage of them better, or better prevent the opponent from using them.
People are stubborn about stuff in this game, and it drives me nuts because being stubborn is not how you get better.
