Batters should outscore pitchers in your league.
My favorite points scoring system for leagues with 12 or more teams resulted in a difference of 8 total points scored between A. Pujols and R. Halladay in 2010. I listed it below:
Scoring for Batters will be: Single=1, Double=2, Triple=3, Home Run=4, Walks=1, Runs=1, RBIs=1, Hit By a Pitch=1, Sacrifices=1, Stolen Base=2, Caught Stealing=-2, Strikeouts =-1, Ground into Double Play=-2 and Errors=-1.
Scoring for Pitchers will be: Innings Pitched=1 (.333 points per out), Wins=7, Saves=5, Strikeouts=1, Shutouts=5, Complete Games=5, Holds=5, Quality Starts=2, Earned Runs=-1, Losses=-3, Blown Saves=-2, Walks Issued=-1, Hit Batsmen=-1 and Wild Pitches=-1
