Wow, I hadn't even noticed that saber throwing was a talent since none of my current players have Ataru. I figured it would be covered under Move's third Control upgrade.
It's also in Shien and Aggressor, iirc. Since canonically we've rarely seen this done (Vader and Yoda in the movies, Savage and maybe a couple others in TCW), I don't mind the scarcity of this talent, though I do agree it seems like something that could easily be done with Move and some narration.
They actually took it out of Aggressor. But I do agree, I like the scarcity of the talent. It's iconic, but not prolific.
However, I don't agree that the Move power is appropriate for this attack mechanic. I like the fact that it's a talent.
