It can only go so far >.< One must think of the position of where to defend, and then the effect of what you did. For me I blocked Cade's blade and used his momentum which more than likely would have had his light saber be pushed up when i defended in a diagonal. I then attacked his left side because if I went for his right and was slow as crap I woulda got chopped down with a vertical slash by Cade in a real battle. By focusing on his left, meant he would either defend or attack. If he attacked me my character's horizontal attack would of went diagonal again with it point to the lower left to defend is attack. Defending... i dunno haven't got there yet but he should be able to do it. >.> I think

(edit: plus thats just me thinking one move ahead xD)
