I like that last one.. what is default fictional? I think default MLB QS is just so someone doesn't get the game and complain about the AI shuffling players around... unless the AI sees true ratings, but I doubt it if you use normal scouting.
I am fighting for a playoff this year though.. so I'm a bit afraid to change them from 50/30/15/5.
My only issue right now is a player here and there being released with decent ratings and good current year stats and last year stats. (which might be something you just can't fully fix)
