In D1 we had elemental primary's in Y1 of D2 these still existed but only in the Energy weapon slot. Then they added special weapons back into the game for those who preferred D1 set-up, so the Energy slot becomes Secondary and can contain elemental primary or special weapon A D2 version of Zhalo would be perfectly valid in the Energy slot. It would be as valuable as any other Exotic Primary that lives in the Secondary slot, there are already many in D2 I get that having 3 Arc weapons in an Arc Burn activity was more valuable in D1. But by definition a Kinetic weapon is a primary without an element so it makes no sense to talk of Elemental Kinetic weapons. In D2 the first slot is Kinetic only
