From rpg.net:
Is the core mechanic broken, it it fixable?
Example: The scholar
Has 20 points of experience and the following dice on an Int test: 5 blue, 2 yellow, 2 white. He is attempting a Hard test - 3 purple.
Taking the test 20 times he can't fail at all. Or mostly ever: 17-18 out of 20, or 8-9 out of 10 times, he will pass it. It is wrong, he is competent, but not a master. For him it's supposed to be a hard task, with max. 60-70% chance of success in normal conditions and max. 80% in favorable conditions. Not 90% chance.
Example: The Troll Slayer
Has 20 exp. Combat Mode: 5 red, 2 yellow, 2 white, 1 purple, 3 black (opponent has shield, armour and dodges).
This one is worse: 10/10 and 19/20. Combat becomes hack fest "who has more wounds" with no finesse.
If you up the number of diff. dice there's no way that a "3-4 blue 1 yellow dice" character will pass such test.
Is this correct? I dislike games that have this 'you are so good you simply cannot fail ever no matter how much time passes'.
