Bungie has said some of these will be equippable but will come with a "major light level penalty" if equipped in crota race. Read: Double/Triple/Quadruple check that you don't have any of these slotted or you might end up getting oneshot and very confused as to why.
Elemental munitions stacked with hunters new strand beyblade aspect to generate ridiculous amounts of heavy. Guess disabling all three new aspects is bad optics so they nuked munitions instead.
