Nice ideas here
This grip of yours that could grip the opponents ankle or some other spot would be really cool
And maybe it would break his ankle (if used at the ankle) so it would be harder to move
And of course the thing that Yoda does in Ep2. We could send the lightningnoobs' lightning back at them
Fear is the way to the dark side....fear leads to anger, anger leads to hate, hate......leads to suffering!
