I wonder if anyone would want to go out of their way to make animations for the shield to do a shield bash, eh?
Could also add a feat like this:
Prerequisites: Soldier/Jedi Guardian;Minimum Strength of 14; Class 10.
Description: Using hidden reserves of strength gathered through many trying battles, you can use your shield to bash your opponent, stunning them for 6 seconds unless they make fortitude save equal to 8+the attacking character's level+any Strength and Constitution modifiers.
Could also give it to npcs. THAT will balance the game for sure! XD
