this is really a matter of subtle shadings; W2 goes into great length (under barbarian) as to these (I don't think you can find this online); barbarous and savage are somewhat more common than barbaric and barbarian to indicate uncivilized cruelty, but all may be used. barbaric and barbarous are more common in relation to taste and refinement. barbaric connotes a wild, profuse lack of restraint; barbarous implies an utter lack of cultivated taste and refinement. I don't think this contradicts faldage...
