The point about combat is a little more subtle than either system. In real life combat over short distances initiative plays a huge part, but it's not the be all end all. Reflexes are also very important. For example say you're facing off with an enemy. You're both looking for an opening, but you're also both wary of the other's potential strikes. If their attention drops for even a second you can spring in and get the first hit. If you're not fast enough or their reflexes are really good they may be able to defend or counter. Over long distances it's much less of a concern. If you charge across some distance towards someone then they're likely notice and either back off or get ready.

The dance would have to be twerking. Since to generate a wave you have to vibrate back and forth.
