situations in which MORE POWER was often the CAUSE of problems, WITHOUT providing any solutions.
Aside from that last part, that's probably the best way to use characters with soooooooooooooooo much power. Then, they would have to reign themselves in as much as any opponents they face. Also, with even greater power, they should have even greater responsibilities. The best issues of Sandman, for instance, were of Dream simply administering to his realm.
