Details make a game to be a great game

And it’s the details that make them different from other games. I would like to comment on some details that the 343 could implement next Halo 5. All thanks to the powerful hardware of the new Xbox One and the infinite power of the Cloud.
I would like to talk about some visual details in the fighting that would make the game more “realistic.” Know when you shoot the walls and shot mark remains, and this effect varies from gun to gun? Then, I would like to see this effect in the enemies bodies. For example: An Elite had their shields broken, you shoot against his armor and some sparks appear (few) and then armor is pierced and the shots make holes in his armor. Or when you throw in his own skin by making blood spots, to show that you reached in part without armor. Elites more powerful (General and Zealot) has a tougher armor (as a second protection beyond the shields). Another effect would be when you use explosive ammunition (Rockets or Fuel Rod Cannnon) and their armor is thrown away and break apart (only the top part from the waist to head), like as with Halo 4 Hunters.
Another effect would be in Grunts: when you hit your tanks methane they leave your back (like in Halo 3) or when you shoot their heads, is bullet mark on their foreheads.
And that’s it. I would like to know the opinion of the Halo community about these effects. Give your opinions and ideas.
