lol, well, then i guess we can skip straight to the chase. I agree with you on everything you just posted, up until a certain point. That point is this: Yes, Mace indeed is not as strong IN THE FORCE as bane. That's fine. I agree that in a duel, mace wouldn't be reaching out and tossing kas'im around like a ragdoll or anything. It would come down to lightsabers.
My argument is this: In POD, there is a quote, BY KAS'IM where he admits that if someone is too strong in the force, all of his superior lightsaber skills won't be enough to help him win. A lightsaber duelist is limited by his ability to use the force. SO my assertation is: Mace is stronger in the force TO THE POINT where it gives him an advantage in lightsaber combat that Kas'im would not be able to overcome. Be it speed, be it precog, be it strength, stamina, what have you.
If you intepreted that POD passage to mean that Kas'im couldn't be helped against a crushing force attack (such as bane's) then yeah, i can see why we aren't agreeing here. But, i'm going with the fact that Windu is superior to the point that Kas'im could not overcome the difference with his lightsaber skills (which, if both were completely stripped of the force would indeed be greater than Mace's)
