Dude, Halo had both heavy and special and it was just fine. The BR primary was the weapon everyone leaned on. Just limit the ammo for both per match significantly: two or three special drops and one heavy per game; and only one person can pick it up not the entire -blam!-ing team. Why reinvent the wheel for PvP? Bungie had the formula and then decided that wasn’t enough, and now it’s like they completely forgot what worked before D1.
