I agree with the not-so random dice rolls.
I've had waaaay too many low rolls on average.
I've taken to rolling actual dice while the computer sims the dice rolls in the game - what a difference! I suggest to anyone to try that and then try to argue that the RNG in game is fair.
D4 dice rolls seems to the worst offenders - I consistently roll 1's when I am using healing potions, greater heal, rolling for weapons etc, AND I've noticed that the henchmen consistently roll 3's and 4's to increase the difficulty to defeat them.
I see far too many 1's when rolling any dice D6, D8 and particularily D12's.
To be fair - I have not played any computer game that relies on RNG without noticing some irregularities.
Just my thoughts and experience.
