Depends on who you ask....gjallahorn was never OP.... atheon, hmg/snipers took him down.. Quick. Crota, 6 rockets of any variety took his shields down. Skolas, snipers and rockets do fine. Gjallahorn made encounters easier but wasn't OP. The community over hyped it but whatever. The true OP weapons were addressed like thorn and tlw. Even final round and range on shottys. Proximity got checked off as well...hell they even buffed ARS and necro... Imo some of the nerf were not needed buy whatever we will wait for the next "op" weapons and use that
