The level 3 Ranger power Disruptive Strike allows you to perform a ranged/melee attack as an immediate interrupt in response to you or an ally being attacked by a creature.
I would like help in understanding what happens when the ranger has a bow and triggers this after being hit by a melee strike. My understanding is the general rule is a ranged attack on an adjacent target allows the adjacent enemy to make an opportunity attack. In this situation that seems a little weird because the enemy was just interrupted, so how can he turn around and then attack?
Similar but different, the ranger uses this power when standing next to an enemy in response to an ally being attacked some distance away. Now it makes more sense for the ranger to be the target of an opportunity attack from the adjacent enemy because he is targeting a different enemy some distance away.
