Heavy bombers were used tactically by the US Army Air Forces during WW2. The most infamous land example was Operation Cobra (Wikipedia link), which saw 1800 bombers from the 8th Air Force attack German forces in Normandy in order to help the US VII and VIII Corps breakout from their narrow slice of Normandy beach.
Among the 500+ friendly fire casualties from that attack were LTG Leslie McNair (Wikipedia link), the highest ranking US Army casualty in the ETO (he was there to observe the effects of the attack - he saw them, all right).
Heavy bombers were used more successfully in tactical roles at sea. As tactics and equipment evolved, planners and fliers used B-17s and B-24s to find and sink German submarines (Wikipedia link) in the Atlantic and used “skip bombing” (Wikipedia link) techniques to accurately attack both IJN warships and Japanese transports in the Pacific.
So, heavy bombers were used, successfully at that, to support attacks on land and to sink ships at sea. I would argue that efforts to nerf heavy bombers are an attempt to “correct” something that needs no true correction.
