How do you declare the terrain for cover?
I've been playing for a while, but I'm still not sure what you would typically assign the terrain features to be. Is every Terrain piece an area terrain feature, so you get cover when you're inside or on top of it? And if I have a table of buildings and barricades, wouldn't all of that be heavy cover?
How do you all assign the properties to the terrain features to have a setup that makes sense and is still fun to play?
