Boost/Roll to counter a Boost/Roll doesn't come close to working all the time unless you're in the trailing position to start with. A ship with this meeting another head on may be using it to arc dodge itself and/or line up a shot on a completely different ship.

The concept of being able to respond to an arc dodger is a good one but I'm not entirely sure this is it.

I wonder if having an EPT that would allow you to delay taking your action until after a ship in your firing arc has acted would provide a similar effect if you're really trying to improve your options against those ships.
