Assasins and daggers
Make stylish way of fighting more efficient
Assasins and thieves with weapons other then daggers look quite unstylish, but most players are forced to use them, as daggers are not powerful at all.
I suggest a slight change in class powers for them: backstabbing for both classes deals 5x damage if made with dagger, 3x otherwise.
Also, assasin's bonus to criticals can be higher with dagger or sword and lower otherwise.
