Me and my regular opponent (my brother) Have decided to play a few games with different cover rules. The idea would be to throw the cover save after the to hit roll, to determine which shots hit cover and which don't. Next are to wound rolls, armour/inv saves as usual.

Now I don't know if the rules concerning cover saves have always been like they are now, but I always felt the current rules were a bit strange, having too choose either the cover save or your armour save. The rules now pretty much implies that a marine standing in 4+ cover is not protected by cover at all, unless the weapon is ap 3.

I'll let you know whether or not it turns out to be a good idea
