It's a newbie trick... A thrown saber is obviously less powerful than a good blow from heavy stance. It's just one of those cheap strats that takes a few days to learn an easy way arround.
Remember when we were all JK newbies and were obsessed with force destruction? Cheap strat, no real skill involved. Easy for a saberist to deal with.
""Ideas are really everywhere. A writer has to train him or herself to look at everything they see or hear with an eye toward "how can I use this, how does this fit with other ideas I've had." There are no lack of ideas. It's not a particular skill to come up with these ideas. The ideas are the easy part. It's taking the ideas and developing them into English that is the work aspect."
