I read a review a while back of Halo vs cod and it said that in cod, you can choose whatever weapons, perks, grenades, etc, that you want and spawn with it. That makes it totally uneven for the players. It also said that in Halo, every game, every player spawns with the same thing and its up to them to find the weapons they want as fast as possible. This makes the game totally even and fair. Now with armor abilities its kinda just like cod where people spawn unevenly and its unfair.
