Destiny already seems to have its own formula, that is using a Primary for regular Gunplay, using a Special for a quick elimination, using abilities to ease a kill. I'm not going into what is currently wrong with that formula, as everyone has different opinions about that. If I would want to make it close to old Halo's Golden Triangle, I would make it like this: You start only with a Primary weapon. Special and Heavy Slots are empty. Personally I would prefer a standard weapon for all players, like the Khvostov, but I can understand if people want a little customized loadout and choose their primary type. Maybe only allow the White Rarity Primary Weapons Grenades are only the regular type grenade like the Incendiary or Flash Grenade, but without an added effect. Suppose Fusion Grenade as stickies work too. Melee is only regular type with no abilities. Jump abilities disabled. Super disabled. You could basically use the "No Light" Subclass here, that was a thing when you first lost your light during the Red War Campaign. Armor mods disabled. Special weapons regularly spawn on the map in form of an legendary engram. Due to currently existing game mechanics they should be automatically equipped as a energy weapon, with little ammo. Also due to current game mechanics, eliminated players won't drop special ammo when killed unless they also had a special weapon, limiting the amount of ammo available. Heavy weapons rarely spawn in form of an exotic engram. Should be a powerful weapon worth fighting for, very limited ammo. There would be need for a mechanic where these weapons would be unequipped when dying. Maybe respawn players in a default state. Damage values can stay in current state, but maybe Momentum values would be better so that people won't constantly run away from fights and the game evolves into a hide and seek. Game Mode Clash.
