Ah there it is. Ok so it seems like the general rule is that a trained character with an 18 stat should succeed at easy 75% of the time, medium 50% and hard 25%. This seems completely reasonable until you have skill challenges that require twice as many successes as failures.
A simple band aid fix would be to simply change the complexity rules. Require 4 successes before 4 failures and you should see average skill people completing their tasks half the time while those with extra skill bonuses will have a chance to shine.
