So I was in the shower and I had an idea: what if elemental primaries returned to the hard raids and ToO Adept Weapons (and maybe PoE too)? How could that be balanced? The answer is pretty simple. High tier primary weapons will come pre-equipped with an intrinsic elemental perk. When disassembled, they will yield a 'generator' item of the same element that can be used to make any legendary primary an elemental one. The system would be similar to the ornament system except each generator is single use and locks to the weapon, becoming the intrinsic perk. This process applies to high tier weapons as well, but not exotics. Weapons with elemental generators equipped drop either generators or 'broken generators' when disassembled, depending on how convoluted bungie wants to make the process (broken generators need repairing from a vendor). Using this system, elemental primaries can be brought into the game easily and distributed well. TL;DR Elemental primaries drop from high tier sources (HM raid, ToO flawless, lvl 42 PoE). When dismantled, they drop a generator that can be equipped on any legendary primary to make it elemental.
