I don't think its a good addition to the Action Menu. What sort of interface would people like, to select/deploy it? If you've seen a good interface for deploying sandbags on another gamemode or server, let me know. There are no plans to start coding it yet, but sketching together some thoughts of how to do it properly, so things are speedy and correct when the time comes. In-game item which goes into your backpack is out of the question, as this requires patching and addons, which requires people to have the addon to join the server. In the interest of keeping vanilla and accessible to everyone, would be a virtual item, when used a sandbag is created, perhaps with some ability to move it prior to placement.
