propose that "Marvel Time" in it's current incarnation is holding the Marvel universe back in a big way. It's the main reason for retcons and prevents both new and old characters from developing. Now because comics come out monthly real time is not an option in these decompressed days. But the current frozen state of the universe is getting very boring. It's like nothing matters anymore because everything is happening in the same year. A year that keeps repeating.
As such I reccomend one year Marvel time be equal to ten years real time. That way it would feel more real again.
Plus it would be a chance for an event story to explain it all that really would live up to the phrase "The Marvel Universe Will Never Be The Same Again!"
