That said compared to The Hulk, the special character required mission sure is actually quite challenging and nothing like the free points for just having The Punisher around. Given IW basically does nothing, the IW required missions are only slightly easier than the hardest mission and give a corresponding less amount of points, so the risk/reward is still relatively balanced.
