Faster door breach
On most doors or fences there's more than one place to access it's action, that is to open or close set door or fence ranging from 1 turn the 6 turns. I would like to have the option to put more than one person on the door to speed it up. I understand the suspense of having two survivors fighting off the approaching hoard, as the other frantically tries to open a door.... a good assault or even a warrior can hold off a crowd. If you don't like that idea. How about armor with lockpicking skill trait. Or perhaps even a shotgun with a breaching chamber.
