I like primaries that do elemental damage. But having a kinetic gun with elemental damage can't limit the weapons usable. Currently using the supercell I can get ark precision kills which works with some of my armor. I think it's cool, but it's not designated as a ark primary. If raid guns had similar attributes I would be ecstatic. I don't know how the actual numbers crunch out with this type of gun but maybe primary weapons with the chance to cause elemental damage might be a legitimate compromise between bungie's plans and player expectations.
