Logistic shortfall shit

[leonard]

Most of the time, I'm playing PG with a friend, face to face. We especially appreciate Hidden Units, Fog of War, Random Events, Mired Units, Smoke, Move and Fire and we are usually using every optional rule possible.
However we have decided that the "Logistic shortfall" rule is not well done at all. 

The rules suggest to use it whenever you want and not only when it is included in the scenario special rules (because one side should be affected by low ammo, low fuel, as historically). So the rules provide a random system : whenever you roll for Fog of war (3 dice) and obtain a result <5, your side becomes affected by logistic shortfall.

We have tried repetitively : in 5 or 6 scenarios in a row, it happened to at least one of us in every scenario. In some scenarios, it happened to the two of us and sometimes with critical shortfall. And this for no historical reason at all and even when just starting a scenario, on the first turn of a huge pre-planned assault. The probability that it would happen is clearly too high. It has no sense, sorry.

Is anybody else using it ?
