No clue why this isn't already a thing. Cause In real life it's not like your opponents lineup is a secret..
All I really care about is the pitcher. Not being able to see their pitcher is ridiculous and can dramatically screw up your game.
For example I have Harper, Griffey, Ohtani, Seager who are all lefties and I start them every game. But if my opponent is starting a LHP, then I wont start all 4 of those guys cause my bench is really deep and I want to be able to play matchups later on in the game if I have to.
But since I cant see my opponents SP, I am forced to either start my lefty batters against a LHP and be at a disadvantage. Or I can put myself in a better position and once the game starts i can substitute in my right handed batters but then I lose those left handed hitters the rest of the game.....
It's absolutely stupid and makes zero sense to not show the pitcher.
It makes sense if you played DD several years ago when this was a thing. Lefty pitcher would see 8 righty hitters. Righty pitcher would see 8 lefty hitters. You need to be able to hit same handedness and I think this way is better than the old way.
