I'm the Michael Jordan of gaming, so what to do in this game now?

So here is where I am at. I have beat it with two toons, done pretty much all side content on each and am looking for a challenge, I tend to like to do things the best there is in gaming, hence the Michael Jordan analogy. I understand that it isn't the same thing, but the comparison fits fully. It still takes a sharp brain, lightning reflexes, and the skills to critically think / adapt. I just do it on the games as instead of on the court.

Anyway, can someone find a challenge for me here that would keep me semi entertained for a day or two...Something only the pro-est of pros would dare try! or some thing I maybe haven't discovered yet if that's possible. I am open to any suggestions, thanks!
