I think the cover-section of the rules is lacking some definition of when units are in cover. Sure if all models are clearly in cover, it is not an issue. However, what of any other situation?
- Should I do model for model, and if a shooting model can see at least one model in the target unit without cover, it is then without cover? Or do you suggest a 50% in cover rule?
- How much of a model needs to be in cover to claim cover?
- Can the shooting unit ignore cover from terrain it is touching (like a low wall)
Would be great if you could include a small section on cover saves in the next update of the rulebook.
I also think the 40k 4th edition rules for area terrain would fit perfectly with the simplicity of GDF: You can see up to 6" into / out of area terrain, but you cannot see through it. (you can see taller units over it of course. Simplifies the need for LOS blocking terrain, as any wood and ruin is now LOS blocking regardless of windows and trees.
