So Luke Smith stated that elemental primaries will be left behind since they lead to a few select weapons becoming top weapons.
I say that they should make a consumable that is only obtainable from hard mode. This consumable allows the user to give a random elemental burn to a primary of choice.
This would give us a reason to do the hard raid like the other hard raids (to get a elemental primary). Plus it would give us elemental primaries that we want. And finally there would be a variety of primary weapons. We would give these consumables to our favorite vendor, raid and even strike primaries.
