Wait, you're saying endgame is too hard because you can't field the people that are familiar back to back every week? I think you're missing a key concept of this - you will not progress without a stable team. Make a free company, pickup your groups. I've gone through the entire game with the same people up to turn 4, and you know what? The fights are difficult, and sometimes frustrating, fights break out, people rage quit, but that is what makes a game good. Don't come round here trying to ruin my fun
