I just thinking about this when I loaded up my first save in FM24 and straight out of the box there are 3 players out for at least 4 months, including a torn achilles for my first choice keeper, who is out 7-9 months. I don't think I've ever encountered an injury of that magnitude in the game, and I wish they were more frequent, if not just to make the game more challenging, but also to add another element of realism and unpredictability into the game.
And I don't think increasing injuries would be all bad, either. As a silver lining, it would also help me give more playing time to younger players who may not otherwise get a chance to get those minutes and help their development in the long run.
