Question: If I ready a daily or encounter power to trigger on a certain condition. Such as the fighter power Sweeping Blow with a condition such as to trigger when 3 or more enemies are adjacent to me. If that condition never triggers do I still expend the power?
I know I lose the action, but it seems harsh to lose both the action and the power (I realize this is a rare case, and probably a poor example, but I can see it coming up with other powers as well).
