There'll always be a meta, some guns will always outshine others, nerfing x and y will just make Z more popular. I don't think nerfing NTEC is an option, buffing the guns that don't see much spotlight for obvious reasons seems like a more viable option.
But HVR, HVR is always Z. It needs reduced damage on every range, because the alternative, damage value's changing depending where you've hit your target, would be impossible.
