They tested a change which made drag looting stop your character movements and play the pickup animation every time. It felt absolutely awful, and thankfully never made it off test servers.
I suspected you were referring to that, but I wasn't 100% sure as it never made it to live so there never was any change to looting. This upcoming change won't affect drag looting, at least not based on text, and only if you use F looting.
afaik they still intent to kill drag looting down the road.
