ok at the end of reach when noble6 was fighting off the covenants every time he took dmg his visor would get cracks and damage. i was thinking if u brought that into halo4s gameplay it would bring in something new to the game. u would have to pay more attention and focus more on the game with cracks all over ur visor.
about the br and dmr i was thinking of switching it up and maybe combining. your haveing a br battle and they run and u want to finish that shot so u hit a botton and it makes it to where ur br goes into a single shot to finish that last hit for the kill. burst shot for a better close range fight and switch to the single shot for better long range fight.
