I'm not sure if someone else has posted this already but I think barbed wire should be left in the game for its many purposes but a tool (potentially the toolbox) should be available for use in taking them down. Now obviously there should be a delay to taking them down (just like the time it takes to put them up). The wire should also be updated to restrict zombies just like sandbags do, or atleast cripple their legs or hurt them. If you remove them from the game all your doing is limiting another way for use to baricade ourselves from other players or zombies (if updated). Yes there are those who are just trolls and will use the wire to block off the stairs to a firehouse with an 870 on the other side just for the kicks to watch the newly spawned player fail misserably before he picks them off from long range or just lets them run off.
