A sane Lancelot wouldn't be very good for any of the characters, considering that he was the greatest Knight of the Round Table. And the Mad Enhacement doesn't exactly make him less deadly. Along with his Knight of Honor and For Someone's Glory, he's pretty deadly. And, if he was sane, he'd be able to use his For Someone's Glory freely to change his appearance.

Yeah, it didn't make Lancelot any worse. However, it did nerf his successor, Herc, in that it locked away his ability to use the Noble Phantasm Nine Lives. And Lancelot changed into anyone he wanted anyways (Et tu, Rider?) 

In any case, due to the all encompassing nature of what I'm about to do next I'm gonna wait for more people to post, including our Co-GM, before I post.
