Skilled Heavies are seemingly immortal . No other class can survive 5 grenades in the face and potentially live . To many people , it seems death is either unavoidable , or killing the Heavy is impossible without a ton of teamwork . The sheer idea of you can ' t do anything without some help is why people hate fighting heavies in particular as opposed to a pocketed Soldier or Demoman which do not have this same problem . If I ' m fighting a pocketed Soldier as a Scout , I have somewhat of a chance to kill them both if my aim and movement is better . However , if it is a pocketed Heavy , the chance of me killing that combo is less likely . This large HP pool large knockback and damage means people will get very , very salty . The interaction itself also seems unenjoyable . You ' re dodging away , hitting your shots . He just stands still and mows you down eventually because he has 99999 Hp left . This tilts a lot of people .
