yeah well, gotta play your chars by their characters. Luke for instance probably had the authority to organise people, due to sheer skill in survival and shooting, but it's simply not in his character to take charge. so sure, he could've put up a better coordinated defense, but then it wouldn't have been Luke anymore. i prefer integrity over survival. also in my opinion, communication was the greatest problem, not organisation. but still, no organisation is possible without communication.
