The things I'm looking to remove are mainly bypasses and nigh unraidable defences. Bypasses are able to 'exploit' the world border by shooting beyond it, since you cant build walls beyond the world border all your hard work has been for nothing. To be fair though, these kinds of cannons are pretty rare but should be disabled regardless. The ac 130 is a cannon like these, it's schem is readily available. Webs should be fixed because the other special block defences have been fixed: brewing stand, enchanting table, chests, soul sand etc are much easier to cannon than webs and were patched on this server, so it only seems reasonable that web defences aren't allowed either.
