Balance in Heroes 5.

Well, probably only those who constantly lose will object. But the problem isn't in the balance, it's in the player. Of course, no one will blame themselves. In general, instead of complaining about the balance, you should look for the reasons for the defeat and change something. Although, of course, it is possible that some races gain more advantages than others over a long game, and it is more difficult for some races to play against some races than against others. But this is not a disbalance, but simply an error; the races are too different, and there will never be a perfect balance.
