Weeeeell... its just a quick idea i had. I guess a huge downside of that would be that clans then would just recruit or create lots of capped fighting chars with LE that then fight for the clans in OP-fights. Without penalties they would have a pretty big advantage there and would soon become the standard strategy.
So it may require the nerf that LE'd runners can't spawn on Undergrounds or OP-GRs at all...
