Talking of oblige publicity, what I would love to see is a competitive speed run between top doom speed runners on an oblige wad none of them had practiced on. Not that I would have any idea how one would organise such an event.
Concerning map one guard monster usage; I kinda feel that it should perhaps be influenced by the map size. On a small first map, it is weird to be facing such big monsters so quickly, but if you make a full wad of huge+ maps, a few tough monsters make much more sense on the first map.
Maybe adding a special case for map one (or early maps in general), when the map is small, would be the most efficient solution.
