So what, it happens. Random statistics are an even bigger obsession. Let's now ban psychology for everyone who isn't a psychologist by education.
Why are you so fixated on your percentages and randomness? It doesn't bother me at all. The main thing is that one side isn't outrageously overpowered, and the others are left to suffer in its shadow.
Otherwise, whether or not to include an element of randomness in the game is entirely up to the GM. If he sees an interesting game in his setting in this way, then what's the problem? Even though I'm upset about the lack of players and I would really like to play with the same Yashur, I believe that the setting should remain as it is. If a serious imbalance is found in the game, then yes, it will need to be addressed somehow.
