In the past Batman has been shown to be very strong as you all know. I have no trouble with his almost super human strength but one thing always gets to me. Batman has fought many people with super human durability, strength, and sometimes even invulnerability and defeated them. He usually defeats them using skill, tactics, smarts, the environment, and his gadgets and advanced technology. That is fine with me until it comes to the part where using his strength and fists alone he manages to hurt or even KO super tough bricks and invulnerable people. If it was someone who's strength was just above peak human like Deathstroke then I could believe that but when Batman is hurting villains like Killer Croc, Bane, and Blockbuster who's strength is MANY TIMES the limit of Batman....... I can't believe it. If you can shrug off rockets and lift up 10 tons easily then no matter how hard Batman punches you it SHOULD not hurt. Batman's arm should break when he punches someone who is invulnerable or is extremely durable.
