Crikey Turnip. In WHFRP 2e it's even worse for whiffy dice rolls. The opening intro paragraph has a tale of a pc making lots rolls under 35% or something. Not gonna happen.
The setting should be grimdark, not the system
One thing a lot of systems seem to be super-shy about is giving any reliability to skill rolls, especially in combat. Its one thing when an opponents defenses can make things hard, its another when even the baseline requires a lot of semi-Hail-Mary's.
(Depending on background, this could happen with some editions of RQ).
