The difference here is that counter-attacking rely on opponent's strategy.
So, Power-Theatrics just can't build a strategy to be equal effective against all types of Wars , for example. That's why even Arkal can't have stable results against Toros. Arkal is able to build the strategy against Toros, of course. But he will lose to the rest of BG-Wars then.
But the dodge will works anyway. Regardless of the opponent. Except the cases when this "RNG-collapse" happens.
So, Rage-dodger can't control his "luck". But Power-Theatrics are able to choose which type of opponents he will loose...
