Exactly. I don't know about disregarding it, depends if you want to pass it along to others, but the idea is not to get stuck in that phase of the training.
Regarding structure, it also changes depending on the circumstances or "environment" we are in. A building has to have a soild earth foundation below the built foundation to be stable. This is not guaranteed when you are fighting, as you can be stable on a nice clean level concrete floor, but when you are put on the grass just after a rain storm or a ice covered parking lot, that can change everything. Luckily the environment will also effect your opponent, so it's even regarding that variable. The thing I like about the WC concept of it, is that it is efficient and does not require alot of larger movements to work. There's no dancin around when using the ideas properly.
