Additional cover rules?

[Mrcellophane1978]

Does anyone know if there are any custom rules about cover that are commonly used? It seems a missed opportunity for there to be so many options to use cover but the only impact they have is to protect from being attacked when 100% of the figure is hidden but you can be attacked if a toe is pointing out with full strength.

I was thinking of a new rule "if more than 50‰ of the defending units damagable area is hidden by cover, the defending unit adds 1 to their defence dice."

Or better

"if more than 50‰ of the defending unit is hidden by cover, roll the d20. If a 15 or higher is rolled, add 1 to the defence roll" thoughts? Thanks!
