The two most significant changes to the overall balance are the ones we made to the melee attacks and grenades. One of the reasons Halo is special is that it has damage spikes. In any given situation, you can choose to melee or throw a grenade instead of shooting, and if you do it right you get a big jump on your opponent (when you dont just kill them outright.) We wanted to emphasize these damage spikes relative to the bullet-hoses, so we made them do more damage. For example, now if someone charges too close with dual SMGs you can melee them and actually kill them faster than they can kill you. You have viable options again.
Sweat mother of meat!
This is great news to all halo 1 fans. Now the single wielding, gernading, melee happy, skilled players will not be beat by the duel-weilding, bullet hose, spray and pray neophites.
