If you know me at all, I've never been in favor of removing injuries from BB and agree that cases of being lucky or unlucky with injuries in the game are good. This case, as you mentioned, was very unlucky.
My point is : if you can get lucky, you can get unlucky. Or very very unlucky in this case. Luck is part of sports and part of games. But in BB, we have the unique ability to increase our luck (doctor, psychologist...) which is very rare in games. So there's really no reason to complain about this
My point is : That can still exist in the game, while limiting the number of days that a player can be injured if the manager made the explicit effort to pay tons of money for a high-level doctor. I think this manager is well within their right to complain about this. If their players had suffered the same injuries and they were only carrying a level 1-2 doctor, I would feel differently, because in that scenario that would have indicated that they put in no/very little effort to avoid/reduce injuries.
BuzzerBeater used to have 7 week injuries in the game as well, but that was reduced dramatically and now you never see anything more than 3(ish) week injuries. This was done because injuries are mostly random and uncontrollable and 7 weeks was excessive and significantly reduced the manager experience. Why was this changed if "there's really no reason to complain about this"?
Two things can be true:
1. Injuries reduce the BB manager experience
2. Injuries and the aspect of luck when dealing with them in BB should stay in the game
It's about finding a balance that makes the most sense for manager experience, realism, % of luck in the game, and user-base retention.
