I don't understand why this added depth would hurt the game in any way or play so drastically different. If something like this were implemented I doubt anyone you play with in BTB would even realize such changes were made. You run around ARing and swapping beatdowns never once realizing you did slightly more damage cause you accidentally sprayed a few bullets in the head before each of your corpses few apart. I can't see anything to fear.
I wonder how much of the decision had to with the limitations of having all of this depth with online play. With PC games, I think you can have this depth because people really only play on servers close to their location. I used to play Counter Strike in an East Coast server exclusively. Halo 3 struggles at times with 4v4 matches from people all over the nation already. I think if the system were to be even more complex it could potentially be a mess.
One example of how this already happens in Halo 3 is in MLG, you can get 2 direct shots (head or body, it doesn't matter) with a BR and then beatdown and get the kill. When you play online, the chances of this working like it should are slim. To make up for this, I always go for the 3 BR hits and a beatdown to be safe. I'm not 100% sure exactly why this happens. Chances are all bullets from the BR spread are not registering because between the time all of the information is sent from you, the enemy, and the host and back, there's a difference in what you see and what actually is going on. Because of this, a single bullet from each spread could miss (in my experience happens a good portion of the time) leaving your enemy with more shields than you think. AKA Lag.
Just picture the AR with the amount of bullets and spread. How many hit the head? How many hit body? How many missed? This could be awesome locally but online it could be catastrophic. Instead, Bungie has created a really simple combat system that is accessible to many and decent to handle in online situations. Where does the depth come from then? I think it comes from the fact the Halo by nature is a very team oriented game. I think it also comes from the maps and the spawn system.
