Also the playtest example is with 1st level characters. They don't need to be high level to counterattack. I think a counter attack is a type of immediate action. You get one immediate action per round. Think about the dragons extra breath attack denies the dragon the ability to tail swipe the flanking rogue because he used his immediate action for the round.
I think Second wind is an immediate action as well.
