So I know you all hate Imperial Kath ( or most of you ) but i think this list may change your mind:
Kath Scarlet (Imperial) (38)
Mangler Cannon (4)
Gunner (5)
Predator (3)
Use predator to purposely miss first attack and use mangler to hand out stress, then trigger gunner and put a crit through on something. If playing against Soontir, Vader, etc... you can shoot at them and miss, hand out stress, which makes them actionless next round and easy to hit, then trigger gunner and shoot at something you can actually hit.
