What bothers me a lot in KotOR is that as you fight one enemy, the others just sit there hitting you, and you can't do sh1t about it. I think that there definetly should be the ability to fight and defend against more than one enemy. You can use powers on one or more enemy, but never your lightsaber or other weapons. If this was implemented in the game, it would make for some cool animations too. My idea was that using two sabers or a double bladed saber would increase your defense against more than one opponent, using one saber would make your defense high when fighting only one person.
I'd also like to see the ability to use different force powers at the same time, as Malak did, against those two Jedi. He cast Force Lightening while using throw lightsaber...
