there's been a lot of confusion about this. i've heard mixed things from mixed people, but what i've always stuck to is no warding the house either way...because people are fucking morons. like this cat here. you know people are gonna run into the house on the cs_ version and throw wards down and then just say "OHHH I THOUGHT IT WAS DE_, SORRY!"
yes, it makes shadow hunter virtually worthless on that map. well that's the way things go. rapscallion is worthless on every map and that's not getting changed either.
regardless, i always warn once or twice nicely about that rule. nobody does it after that. however laying the wards in the ct spawn area is against the rules on this map because that's a bomb site.
