Both a strength *and* a weakness, IMO, is the d20 roll damage system. At exactly equal PL, you'll have a 50% chance of inflicting a wounded condition, and a smaller chance of wiping the target out completely. If the minion is half the PL, he's going to have a smaller chance, but on a d20 roll, he's still got the chance to roll well, or the high PL foe has a chance of rolling crappy to resist gaining a wound. It is *possible* for a PL 5 minion to wipe out a PL 10 hero, if the hero just blows his roll.
