What it would do: Basically this would protect an area from explosions unless the defense is destroyed (the defense itself is outside of the protected area nearby and can be blown up). Ideally there would be permissions and a restriction for the size or an extra cost for larger sizes. The defenses could be defined via a command and right-clicking a specific block, then setting the first and second position for the protection (must be away from the structure). Why I think this plugin could be interesting / why I think its important: Factions right now, on a lot of servers, due to the availability of obsidian, TNT, spawners, etc., has really no strategy at all, and its getting kind of monotonous. A plugin like this could make Faction betrayal harder (can't explode stuff from the inside without removing the protection), and would break the monotony, as farms, houses, castles, etc. can be built without the fear of someone creeper-ing/TNT-ing them easily, and the focus of Factions won't be on the boring job of building walls. It would also add key strategic points that must be destroyed/defended in raids or raid defense.
