Really Alexis? My continuing to present comments on your arguments isn't baiting. Turn off your comment box if you don't want comments.
Other people have been using monsters with only one Hit Die for decades now. Other people have thought about what that means. Other people have done analysis in different scenarios. Other people are playing out different scenarios.
The basic data is 1HD monsters in AD&D have 1 to 8 HP. A DM can think about what that means and think "no way the Orcs of the Black Hills have only 1 or 2 HP they would already be dead" and do some analysis on that and realize it makes more sense for them to have 7 or 8 HP as all the wimps would have been weeded out as analysis of the data would show. That analysis is based on a specific set of conditions/scenarios which is clearly not exclusive in a game world where 1 HD monsters have 1 to 8 HP.
A DM should play the monster appropriately, the 7 or 8 HP orcs aren't the same fellows as the 1 or 2 HP orcs . One scenario to explaing HP scores is inadequate to explain the range of HP scores that exist even in but 1 HD.
