It isn't so much the building of the character, but when I tried to do it based on Michael I found that I didn't feel I did his diversity of skills, and the ability he has in them justice. I found myself saying well I could forgo this aspect of his abilities or make him not as good here. Long story short I just didn't feel I did him justice with only 400 BP. I know Michael isn't a beginning character, but still didn't like how any of my attempted builds came out.
