I have become used to the way this game works, but it’s still right what you‘re saying. I didn‘t want to lose my cup-game last Thursday but I also needed to win my two home games in the league in order to have a chance to stay in the league. I still tried to win but my subs weren’t good enough even with HCA. It‘s possible to play all three games with starters and train gameshape - but that‘s not a permanent solution. And it‘s also possible to have a very big roster with high salary-players - but that‘s impossible to sustain for a long time because of luxury tax etc.
But like you: I don‘t have a solution for this. The solution for myself is to decide beforehand which is more important to me: cup or league. And I usually decide for the league...
