I know this is old news but I've been festering for years on this.
Blood Bowl 2 dice rolls are rigged. The development team must be lying.
I think the problem is that the dev' team has not employed anyone who knows how to make decent AI for such a game. It is indeed very difficult; too hard for these folk anyway - as you can see if you play the game. The game's AI strategy almost never extends beyond "making a cage" - even on the last turn of the half; which is comical I must admit. But also its boring. Once I saw an elf pass the ball - once!
I could definitely do a better job ... and have! I don't mean it arrogantly; I just mean the bar is so damned low that my last nostril excavation serves as a better Nurgle strategy than the game's failed mulch.
So they compensate by rigging the dice - that is sad. AI design is hard but possibly the most satisfying aspect of tech dev ever. It's my passion, so this knackered version of a great dice game upsets me greatly. I want the damn job - no-one else appears to be doing it!
Dice rigging! That is shameful and tragic. I know the money men kick them in the balls daily and that there's never enough time - I'm sorry life in that organisation is so visibly awful. Perhaps GW should find a different studio for the next version and just use the awesome graphics team, voice artists and script writers; the people who didn't drop the ball just short of the touchline.
