it has been tested over and over, with programs calculating the dices, how likely it is to have a winning/losing streak, etc.
and over and over, we have come to the conclusion that, yes, the dice are balanced.
so it is most likely that any imballance you see in the dice are the result of subjective thinking.
whenever the dice go well, its only natural, but when they suck enough to lose a game to it, you remember it.
believe me, i've had my share of bad dice too, but unless you can come with actual proof that the dice are not random enough(statistical proof, not one odd example
