Fatherdog - I agree that all those need to be worked.
And I would also agree that rules such as stopping after the point is scored encourage people to do things such as flying backfists, and that could be habit forming, as well as a complete waste of time.
So yeah, in that sense point sparring is pretty, er, pointless.
But I do think that medium and light continuous sparring are useful tools for training bridging techs, rhythm, timing, and just trying out new things, without the threat of a broken nose or something. Following successful application in this "safe" arena they can then be tried in an "unsafe" arena ie. full contact sparring.
I think I misunderstand people's dislike of point sparring as a dislike of any non- full contact sparring, and that is the context in which my previous comments were made.
Shouldn't assume such things really.
