Real problem in the game is Game Shape Training, way too strong, I think that you need to focus into that, not in a tool that has no mayor impact in the game.
The "empty lineup prevention" is just a tactic that doesn't allows you to control the minutes, is an easy counterable tactic, but game shape training is not. I think that you need to hear the community. just search for the topics that talks about game shape unbalance.
