Agree to disagree, I think everything is based on execution and intent. Marvel can definitely keep Adam a powerhouse hero. You just can't make him solely an earth based hero. I would love to see Adam as the leader of a team of earth heroes that truly delve into the cosmic. I guess something like The Ultimates, but closer to SHIELD. I think this would enable Marvel to keep Adam right where he's at. Knock his power too far down and anything below Thor level, he will be lost in the scrum of many other characters. Adam being a minor character is subjective.
