I think telling the Queen to not solely push 3 M56D in a corridor could work as well!! Now seriously: as in movies, marines are supposedly to be unstoppable in a wide/corridor front charge. That's the reason xenos grow their hives in caves with lot of flanks to attack from. This nerf feels like you did a bad push as Queen and then proceed to blame the M56D users because they were doing their purpouse perfectly: cover an area. In addition, boilers exist to push that kind of situations.
