I'm not particularly good at swing-blocking and the vast majority of people I duel don't seem to be either as I mblock disarm them often. I don't think swingblocking is as important as youre making it out to be. Spacing, timing, and pbing are more important. Knowing how and when to swing block is important but not "basic", precisely because it is so hard. Something that is "basic and necessary" is something everyone has and you have to be able to do to compete. If you make swingblocking easy, you are in actuality going to be making it a basic necessary skill.
