Great dude! Glad you're enjoying the set. And yes, by all means feel free to mess around with things.
As for the illegal man downfield, I wouldn't touch it for this set. It's on by default in the MM, and off by default in CFM games. If I were playing AP, I would definitely turn it on. It doesn't quite translate to this set... full disclaimer: I only toyed with it briefly. I'm really trying not to mess with much, which is why I decided to leave it as it was. As for what it did, I couldn't quite put my finger on it. Since they still call it in games with it turned off in CFM games (on in the MM), I didn't see a need to screw with the balance that we've created. Game is playing great - why fix what isn't broke?
