barbarians are not ninjas. The way I see it, Their nerve and general combat affinity give them the ability to 'grab the initiative' of combat, and punch the enemy in the faec before he does. If you look at the system, its not really a counter attack, since that would imply the original attack actually hit.
After combat starts, they're just as succeptible to getting stabbed in the back as any other guy. (well not stabbed in the back as that is impossible in SK when you've been fighting anytime soon, but you get the point)
My suggestion would be for counterstrike to be irrelevant to the damage the attack would deal to the barb, since I dont see how a barb can simulate the massive ammounts of damage of a backstab or cleave back to the guy who hits him.
Instead, it should stop (fail) whatever initial skill was used against the barb such as bash and trip, and 'lag' the attacker for 1 round.
Example:

Briareos counters your attack!
Briareos's counterattack does X damage to you.
Briareos's counterstrike sets you off balance.
