I made the move from HOF to legend in my franchise about 20 games ago. Pitching is pretty realistic on Legend. You have to mix pitches and avoid the middle of the plate at all costs. Good hitters are so hard to get out with anything less than an elite pitcher. I've noticed the confidence meter comes into play way more. CPU will destroy the bullpen if they start slow. It took me 5-10 games to adjust but it's very worth it. I play with the Braves and I'm winning about 55% of games since the switch so pretty realistic.
