So several things made me feel let down in a way during the course of Arkham Knight. Nothing however came close to the disappointment I felt upon reaching the Deathstroke Boss fight only to realize it was just another Batmobile encounter. This is sheer lunacy on many levels and the only comparison I can come up with, that everyone will understand, is that this is the equivalent of having the Anakin and Obi Wan fight in Revenge, take place exclusively on speeder bikes. Below is a little bit of the Deathstroke bio, just to explain why this absolutely needed to be a hand to hand combat fight.
Slade Wilson was sixteen years old when he first enlisted in the United States Army, after faking his age. After serving a stint in Korea, he was later assigned to Camp Washington where he had been promoted to the rank of Major. In the early 1960s, he met Captain Adeline Kane who was tasked with training young soldiers in new fighting techniques in anticipation of brewing troubles taking place in Vietnam. Kane was amazed at how skilled Slade was and how quickly he adapted to modern conventions of warfare. She immediately fell in love with him, and realized that he was without a doubt the most able-bodied combatant she had ever encountered. She offered to privately train Slade in guerrilla warfare. In less than a year, Slade mastered every fighting form presented to him and was soon promoted to the rank of Lieutenant Colonel.
