The rolling dice is really problematic. It's rarely "random". Sometimes the frequencies of 8 are much higher than the ones of 6. Sometime the frequencies of 7 and 6 is 7:1 or even 8:1.and the AIs get much more 7s than you do. You always have to spend your resources to purchase knight cards to fight against the AIs' 7s. Otherwise, you are always the one who most get robbed. It's very frustrating.
