The attacks are faster, yes. Serious? Since uke doesn't follow up with anything after each grab and over commits to each strike, I don't think so. And the timing and spacing are totally left up to uke since nage just stands there until uke has launched his attack despite the fact that uke plainly intends to do something more than just shake hands. Uke's body language and movement clearly foreshadow his intent.
Even if you addressed some good points, on that kind of attacks nage has to do some work to throw or control attacker, and not any amount of mysterious aiki bunny hands waving will help much LOL
I'd love to see all you KI masters with uke like that
Immediately all Ki myths would fall down with big noise...
